I took Ed's route about 6 mo ago, went to local wrecker and got clutch and brake off a dirt bike for $20 (no idea what bike, just bought for the folding bits that were similar to versys size). I was pretty fussy cutting off the tips of both shifters, trying to get the correct length and position but not rocket science. Did the clutch, and have tested it a couple of times - effort well spent IMO if you ADV much. A bit fugly, but works well. I held off on the brake due to time constraints, and bent the crap out of it last weekend. So this week I'll do the brake as well.
I also looked for aftermarket options, preferring a bolt on solution - I couldn't find any that wouldn't require mods so bought the used ones. If you don't have a welder, you could probably find a shop to do if you set it up first or might get spendy.
