I have something kind of similar on the go, except I'm making a 3 piece takedown. Riser is red oak that I'll likely do the vinegar-steel wool thing on.
Limbs will be hickory back, maple core, ipe belly with walnut wedges at the riser. I've got the ipe cut and the wedges thinned to nothing. Have to prepare the maple I have and pick up some hickory.
This is a kind of back project. I'm working on my swap bow and have the next build I want to do for myself pretty much figured out. Might be a while before it's done. Hoping to get in the #45 region.
