I figure you'll get a few different answers on this one.. I personally like for my limbs to start out with the same profile, or at least close. Easier for me to tiller from there forward, it is not necessary though. I have a bow I made some time back with a profile somewhat like your picture, a little less. Odd looking at brace, but the tiller is right, or close. My vote, add reflex to one or deflex the other to match in that order.
Edit. Looking at the picture, if you reflex to match, it'll be a bunch.....I'd consider it anyway.
