"I figured the maple would make it bright but with enough mahogany to give the tone some thickness, which ultimately is my goal."
On paper its a great configuration for that.
I dont know how true about reflecting the body tone, if true at all, would be with a through neck. In a through, the through really dominates the sound - the wings arent incuded in vibration transmission. They colour it slightly, but they arent in that loop strings and whatevers between the nut and bridge.
