A bow with that much reflex, cannot be low braced. You can only floor tiller it, and then jump right to a full brace height of 6" or so. But even then, you run a chance of the bow flipping backwards. That's just because you put in a lot of reflex. Personally, I hate to deal with more than 2" of reflex. String bridges will only help so much, in these situations.
The left limb appears to have less reflex (recurve, almost) than the right limb. Not ideal.
Yes, you can steam bend a piece of wood several times without ill effects. Avoid heating the wood more than necessary, but five heat bending sessions should not hurt the bow.
