You'll be able to "easily" customize the GP's harness to fit your needs. The added headache of DBW will require the car's pedal system, too. Just bumped into a guy at the junkyard replacing his GP's TB due to the motor and board no longer working, which is a failure mode as they get older.
Not sure how happy the 700R4 will be getting commanded by the PCM (isn't it a non-electronic trans?). The speed sensor at the output is your primary concern, and the PCM might be configurable to ignore all the errors from not having to run solenoids and such. Track down schematics from service manuai, and possibly ask ZZP if they're willing to work with you on a PCM for your needs (might run upwards of $500 for their default price packaging, when it's all done, though... And they might not want to get too in the weeds on a custom project for minimal return, which costs them time away from selling basic standard upgrades).
This adapter plate might make your job easier, since this FWD bell pattern didn't get into more RWD setups until the 90's Camaro/Firebird V6, primarily (might be available in some non-4.3 S-10's with 700's or 4L60's, but others have that info elsewhere).
