GatorGuy, Thanks so much for the advice and time!!
I think you hit the heart of my question/problem. I was going splice into a line that was already controlled by a valve. You saved me so much time and effort because I didn' realize that I'd have to have that valve open before activating the next valve. Thank for pointing this out now!!!!
On those root zone systems, they recommend three per tree. The idea being that if you water deep, you get good root growth. Nice idea, but a lot of work, because as you pointed out, if you hook into an existing system, something is either very dry or over soaked.
I wanted to catch you all up with my activities and perhaps give you a laugh as well.
First, many thanks for your help to date! I did successfully, reset my my PGP's, PJG's and Sprayers to their proper height. I will mention that in my area, if you want 1/2" cut off nipples, you can get them at Home Depot. If you want 1/2" union's, sorry those are at Lowes. 1/2" T's...back to HD. 1" unions for splices? Lowes. 1" line...you guessed it, HD.
I also added some sprayers. Orbit was all HD or Lowe's carried. What crap! I'll say no more.
After the sprinkler exercise was complete I decided that some electricity at the back of my property was in order. So, I rented a trencher and off I went. It's not like I didn't realize there were water lines down 8" or so, but it turns out the original installer must have been drinking during the install! There wasn't a straight line in the whole yard. So yes, I cut pretty much all of them! I am now quite skilled at splicing 1" plastic line. <grin> And, much learning ensued.
When all is said and done, here's what I found and I'd like opinion's. It seems that 1" line is on the periphery of the yard with 3/4" line "T"-ing off for the PGP's and 1/2" for the Sprayers. If all of this is normal, my question now goes to zones, flow rate and all that. It seems that my yard is set up geographically rather than zones of grass, bed, shrubs, trees. And, unless I'm set for digging it all up (and I'm not), I'm stuck with this configuration.
For my question let's talk about my zones 4, 5 and 6. I have 5 PGP's in each zone. In zone 6 I decided I wanted to add some sprayers for the shrub and flower beds. It wasn't difficult, but I think there must be some math (that I don't know to figure out how many sprayers, PGP, etc. the zone can handle. Can someone point me to that learning?
In zone 4 and 5 I have a tree in each zone and would like to put something directly on each tree for deep watering. Hunter makes a gizmo of some kind for that. Can someone help me calculate that stuff. Likely it's the same math as above, right?
Then as part of what I'd like to add to the system (assuming the flow rate and capacity hold up) are these little micro sprayers and drippers I've seen. They seem like they just push into 1/2" line. However, it seems be a thinner line than the 1/2" line my sprayers are on. Can I somehow splice this type line into my 1/2" line?
I know if time, money and a trencher were at the ready, the idea solution would be to add more lines and zones, but I don't see that happening right now. I've got to cobble together my new needs with my old system, so any and all ideas are welcome.
Again, thank you all so much for your help!!! In spite of the cut lines, I've really enjoyed the learning and had fun doing the work.

Boots is right, though I have seen it done.
Strongly recommend against.
Everything goes back to precipitation rate.
Biggest MP Rotator: max 30', 40psi, precip rate = .40" +/-.
PGP: 30', 40 psi, precip rate = .6" to 1", IF you have a smaller nozzle (1,2 or 3) installed. Bigger nozzles = more water.
Plus inlet size reduces from 3/4" to 1/2"
No you can't - let the PGP heads be
Are Hunter MP's swapable with Hunter PGP's with mod at all?
Huge, huge thank you for your responses and informaiton!!!!!
At the risk of pushing my luck, I do have one final question. Can I unscrew a Hunter PGP and screw in a Hunter MP ith no modification of any kind? I'm reading that MP are the spiffy new upgrade for rotors.
Thanks again for the help!!!
If your sprays for the beds are 4 inch pop ups, replace with 12 inch pop ups. Or use the existing sprays and add risers - lengths of plastic pipe - cheaper fix. Home Depot will have risers that may fit, try that first as long as you don't mind the units showing while not watering.
Can you switch around sprays and PGPs IN THE SAME ZONE? You need to look at precipitation rates - that is how much water is put out to the lawn/beds. They should be similar. If you have one sprayer .5 inch/min and a rotor 1 inch per minute on same zone, problem potential.
