Can 2" thick panels be used at the first reflection points if there are enough other bass traps to compensate?

Yes, the primary purpose of the RFZ absorber is the mid/high reflections so 2" is fine. As you apparently know, the reason to use thicker and/or space the panel a distance equal the it's thickness off the wall is to allow the panel to extend to lower freq.
So the recommendation for the latter is that while you're taking the time to build and install RFZ panels, why not invest a little more time and $ and get the bonus of more LF absorption...because all small rooms can use as much of that as possible.

Both sides opposite FRP are hallway entrances and wife says two 4” traps at both FRPs would make it too narrow or be in the way. She has agreed to 5 other 4” traps besides the four 2” traps, two 2” ceiling clouds above FRP, two five foot storable 4” gobos for in front of the 4x6’ window, and two rear 24” to ceiling corner bass traps. Room is 13 x 18 x 8.2

The panels opposite the tracking area are 4”. Does it make sense to stagger these on each wall for maximum coverage or should 4” panels be opposite each other? If opposite how far should or could they be apart? Tracking area is 6’ x 13’

4" rigid will fully absorb 125Hz which is well within the range of stereo spread. [Reading this back, I'm using 5" woofers so if you have larger speakers and/or ones with greater extension, you still need to be concerned about bass radiation.] I don't believe you can compensate by adding more absorption elsewhere. Elsewhere is probably not at first reflection points. You only get one chance to absorb first reflections! That said, anything is better than nothing.

You gave me an idea to solve my problem. I will install 2” panels at the first reflection point and just put the two gobos at the FRP when mixing, and move them in front of the 4x6 window when tracking. The window is 10’ behind the mixing position

Boom. We're thinking of mounting 'hook channels' into the ceiling so we can move the panels around too.
Glad you solved it. I always have to move panels in my front corner since they block the door. Though I considered a drawbridge suspension, the required moat accessory was a dealbreaker.
