Just keep in mind it's nothing you can publish....SWSE is not OGC.
And since UtF is rather important for determining the effects of any force power or the like, I don't think removing the skill would be a very good idea.... Maybe just rename it Tech Savvy or Custom Tool Use or whatever.
As for teleportation, look to the Fold Space force power in the Jedi Academy Training Manual. It's a power normally used by the Aing-Ti Monks, some alien force-users unaffiliated with the Jedi except for training Jacen Solo in some of their techniques, apparently.
The Drain Energy Force power in that book might potentially represent Starscream's null ray, but it's fairly short range (6 squares, i.o.w. 30 feet) and might not QUITE accurately represent the null rays' effects on Transformers (though it seems adequate for the effect on smaller machines, like a Transformer's rifle or something).
The recent series Transformers Animated, on Cartoon Network up until recently
IIRC, included some things that fit better in the SWSE rules. Ratchet, the Autobot medic on Optimus' team (obviously, his vehicle mode was an ambulance), was a surly doc-bot with a pair of electromagnetic projectors on his arms, which could move objects around from a moderate distance with some kind of electromagnetic beams from both projectors (I don't recall Ratchet ever moving anything with just one projector aimed at a target, anyway). He also had an EMP projector, which fired small electromagnetic pulses at a nearby target to temporarily disable pain sensors and, when turned to full power, could paralyze a Transformer (or maybe it knocked them out, I forget). Prowl was a cyber-ninja (vehicle mode: fast-pursuit motorcycle), who meditated and focused to tap the energies of his Spark, for operation of nearby devices, breaking free of mind-control or paralysis or the like, and a few other feats I can't remember. He called it "mind over spark" I think. He could also project short-range holographic duplicates of himself to trick enemies, and had boost jets for extended leaps and very brief flight (flight was a personal ability mostly limited to Decepticons in that series).
