It is pushing the envelope, but I think it is doable. I use an A riser with no.1 limbs for hunting out of a blind for turkeys. Though my draw length is 28 inches, I sometimes draw the bow to 30 inches or so, and it seems to handle it OK. You will get some stacking, as Seeker points out. Finger pinch might be a more troublesome/annoying problem. But, if you only plan to use it for hunting, you won't be shooting it that much, and it shouldn't be a problem. And if it doesn't work out, you can always use the limbs on your B riser.
You might also consider splitting the difference. Bear is making no.2 limbs again, and there are older no.2 limbs available. that will make a 58-inch bow on an A riser.
