which lens do you have--seems to me the 2d is a perfect portrait machine already--stiff front no messing about with setting it to straight...folds up...light...you want more bellows draw is the problem? that can be solved too without getting a new camera--extension back OR...my favorite..just put a close-up attachment on your lens--front or back cell..if it's a smaller lens PERFECT...then you can forgo the extra bellows draw AND retiain speed....the amount of optical "degradation" from a proxar is negligible in most circumstances, and more particularly, portraits.
