maple fret board

Hi, Anybody ever tried to make a guitar out of birch? ..well i tried and did. A demonstration of this guitar can be found behind the youtube-link below: The specs are listed below: When compared to my guitars with mahogany or poplar bodies, this one has more attack with lots of mids...

It seems that Ibanez just doesnt have a good selection of seven strings these days let alone ones with maple fret board. Does anybody know where I can purchase a new neck for my RG7321 with a comperable neck profile (wizard II) and the maple fret board? Any other suggestions would be nice as well.
