you wouldn't be able to just unbolt it and move it. it plugs into the distributor. you'd have to get a distributor from a 94-95, the wiring harness, a new TFI for that year, etc...
if you really want to do it, its possible to do with the stuff you have now, with the proper electrical connectors, extra wiring, etc.. but it's gonna look hacked.
The problem is extending the TFI harness so that you could relocate the TFI to a cooler spot. As it sits, the TFI harness is way too short to go anywhere else. Cutting & splicing it to extend it may pose problems since you don't see the ground shield that is inside the harness unless you cut the harness up. The ground shield protects the computer from EMI coming from the spark plug wiring.
The PIP module inside the distributor is also susceptable to heat problems. Might be worth replacing that too. Little more involved of a replacement than the TFI but its not too hard.
is the PIP module the same as the stator aka pickup coil? if so, i replaced it a month or two ago and the car ran great for a bit. the problem came back, but not so dramatic as to leave me stranded. now it's just the occasional stutter, buck or shut off.
when hot, the car will hesitate or stutter under load. sometimes at a stop, even with light acceleration it'll bog down and shut off. wont turn on for a few seconds but eventually catches again.
even when cruising in a gear on the highway or street, it'll just hesitate for a fraction of a second. If i go WOT, it'll accelerate, stutter, accelerate even more, stutter, accelerate more. WOT in increments, lol. it sucks.
when cold it accelerates like a champ, no stutter, etc...
it all happens when its at operating temps.
edit : i dont want to throw parts at the problem, but my next guess is to replace the stock ignition coil. If that doesn't solve it, then buy yet ANOTHER tfi module. If that doesnt cut it... im looking for a new dizzy.
seems like my car just has ignition problems!

Not 100% sure,but might wanna put a fuel pressure gauge on there and watch it while you drive,kinda sounds like a heat soak problem with a fuel line.....just throwin this out there??

hmm.. now im stumped. i dont know which direction to take. haha. my coil looks crappy and there are some wires that plug into it that are wrapped in electrical tape. not sure if the coil is bad or not.
are there Fuel pressure gauges that'll reach all the way inside the car or are they only mounted in the engine bay?
i have limited knowledge on how even to work a multitester, but i put the dial on the lowest setting (2) and when i lined up the prongs with the terminals i was getting reading of .289-.3 at idle. Who knows if i even measured it right! haha.
it hasnt left me stranded yet. my symptoms have been different after changing my stator. i dont get stranded for hours while the car cools down. it just chokes and sputters occasionally in gear while driving in the streets/highways. i took pics of my coil to show just how crappy the surroundings look. (like most of my engine bay)
take out the MAF sensor and look into it under a bright light. you should be able to see a couple of tiny wires inside, less than half an inch long. they should be as white as the background of this page. if not, clean them with MAF cleaner, NOT carb clean or brake clean. NOTHING chlorinated.
