I know, I know, it's definitely not going to sound like a Les Paul Standard. But that's the general direction. Gibson used maple necks with ebony fretboards on some of the LP Customs (see Zakk Wylde's) in the '70's, along with the mahogany/maple body, so if I'm ommitting the maple top and using Mahogany (or something warm and bassy sounding), then I'm getting close.
I'm only using the Maple neck because I had it for a few years (from before I knew much about different tone properties of wood) and had to do something with it. With it being Maple and Ebony, it's going to be bright regardless, but I know I want to do everything I can to combat that and try to tame the highs and make the tone more open and resonant.
Previously, when that neck was a full neck-thru (before I cut the body sides off), it was extremely bright and compressed. I'm hoping with less maple (technically, it's now a "deep set neck"), a thicker body of chambered mahogany, that it'll be smoother and more mellow, tone-wise.
I use high-output humbuckers and rather thick strings with a high-gain amp, so that helps with getting a pretty heavy tone. I've considered swapping in an Alnico 2 mag in the bridge to tame those highes and boost the mids.
The Walnut is an excellent suggestion, based on my experience, it and Wenge have a ton of bass, but still have clarity (which would be perfect).
Rosewood would also be good, I'd just need to find some wide and thick enough.
Now I've got some woods to think about. Any more suggestions from out there?
