No. I think its crazy to invest that much time and labor to pull and tear down a trans and not service it while its out. Plus the labor to reinstall it.
Here is my take. I would lose the kit with electronics and just buy the electrical parts you need. Any solenoid should it fail down the line can be replaced from the pan with the trans in the truck.
The next thing is there are a couple of things mandatory during a rebuild. Beast or hardened sun shell is one, that is a known failure point ($50). Check to make sure your kit includes this.
The next minimum step I would take is to replace all the steels and frictions and the band. That kit can be had for under $200. I chose to upgrade the 3-4 stack to 7 clutches from the standard 6 giving additional holding power. I used the borg warner HD frictions. Corvette servo is also a cheap $20 upgrade which will improve 1-2 shifting and holding power.
A standard rebuild kit will include all the seals, pistons, gaskets, plus frictions. You can likely get the monster kit you have listed without electronics for less than $500 either there or at
www.bulk part.com. You may have to customize the frictions if you upgrade the 3-4 stack. I simply ordered one additional friction and some 0.080 steels to supplement what came in my kit.
Edit: also you want a new torque converter to go with the rebuild. With labor yourself, you should be able to do a full rebuild with a torque converter plus your burnt electrical parts in the $800 range
