I'm throwing in with Bubby. Maple,........good, hard, consistent maple is great bow wood. Backed with the oak, OR left in board bow form, it should make you a fine bow.
I'd personally, just cuz I can't stop messing around, cut out and thin-off a maple belly 2" wide, heat treat it (maple takes heat treating well, though it seems to improve it less than hickory or elm, it still improves it), then glue up a white oak backed, maple belly, Perry reflex pyramid rough out, and just mess a little with the tiller to compensate for the reflex. And if I had to, I'd square the side parallel as I go, to 1/34" and see what she gives you for weight.
Hunting poundage in the 50's should be cake.....
