But it would still be a maple neck, no? I think the OP is after a mahogany neck back with a rosewood board.
In terms of tone it should sound similar to a Les Paul type guitar as long as the wings of the body are mahogany as well. You might not get as much bite from the maple cap as you would expect; I think it is the received wisdom that with a neck thru the wood of the neck has much more of a bearing on the tone of the guitar. I personally prefer a set neck to a thru-neck, but if that is what you want then I am sure it will work well.
I would be tempted to add a walnut stripe in the the neck or an ebony fret board to add a little more bite to the tone.
That mahogany/maple/rosewood construction is good, but I think the bottom end can get a bit too flabby, and there isn't quite enough upper mid or top response to be perfect, to my ears anyway.
Once I get the workshop up and running, and once I've made an all Australian tone-wood guitar I am thinking of a similar build, but using a set neck, paduak back with a maple or walnut top and a flame maple neck and ebony board. I think that might end up being perfect for me in terms of the native tone, sustain and attack.
