Has anyone converted a Hasbro ULTIMATE FX Lightsaber to an in-hilt?

(NOTE: For those who don't know, the UFX (Ultimate FX) line was a cheap, plastic version of the Force FX Lightsaber. They shared similar electronics, however UFX featured flash-on-clash, and the soundboard was much less sophisticated, even to the point where the swings and clashes were in a pattern.)

A few months back, I bought the Anakin-Vader UFX just for a cheap saber. I want to convert it, however I'm not sure how I should approach this. Several wires on the inside were also unsoldered, not sure where some link up proper.

I just want to know if anyone ever converted any of these and if I should even try to, and tips if I should. It'd be the first conversion for an UFX I'd have ever seen.

I am also looking for some help remaking a saber. I have a kylo ren ultimate fx lightsaber. Any luck finding people that can help with these boards?
