I see your point, but really, if we're building a team the way you should (non-overlapping expertise), if you have a lightsaber combat character in the party their *job* is to do the awesome combat thing. If your character isn't built for combat, then whether or not there's a jedi in the bunch you're going to feel less useful in a fight (in two of the games I'm in that are active my characters are social characters. When blasters start firing, I tend to hide and let the brawlers and shooters take care of it. They do the same when it comes to investigation/conversation, where my character's shine and I take centre stage).
Anyway. I'm not keen on making a 'lightsaber woodchipper'. I was planning to use a lightsaber, but mostly because our crew so far is a bounty hunter and a doctor. Figured someone with a 'breach' melee weapon with a focus on blaster deflection might prove useful (and because then I could build the character around one stat: Cunning; but only if I use a ligthsaber).
That said, I'm happy to not go that route if you feel that a lightsaber in the house might edge in on your character's territory in terms of expertise (honestly, jedi are 'balanced' fine, the big issue is the sabers and specifically breach). To be honest, I'd be surprised if falryx let someone start with a lightsaber anyway. In whcih case, I'd go for a straight up Sentinel/Shadow built to be a force using ninja and rely on a blaster for fights if it comes to it (but, in fact, build more towards non-combat oriented stuff; knowledge underworld and sneaking about).
