I've made a few bows from it, and I have messed with heat bending, twisting, recurving, trapping, etc.
I always use the older, knarly staves and those have their problems that limit performance but look cool to me. I've seen your staves and I think yours are more ideal.
Still, VM is not osage, in general, although some staves are better than others. Oceanspray, on the other hand, is another story.
In general I would keep the dimensions somewhere between osage and hickory.
I would not violate the back without backing.
Responds to corrections well but sometimes fights you.
Responds to trapping and heat treating.
Make sure its dry.
I'm looking forward to seeing how your bow(s) come out.
