I re-barreled my '06 to 6-284, its an almost ideal starting point IMHO. Same bolt face dia (because the 284 is rebated), you have the extra length I personally think is necessary to allow the LONG bullets to seat where they are supposed to & mine feeds flawlessly... OAL with a 107SMK is just under 3.100 somewhere (can't exactly remember).
I would have to say green light, I'm no gun-plumber by any means but a new tube should be darn near all you would need as far as serious hardware.
