As I mentioned on January 24, We haven't done any tinting or dyeing of wood, and on February 11 I told you, We shy away from dyed or tinted wood, and recounted a horror story of one experience of using a pre-dyed commercial product.
Is is possible? Yes, I'm sure it is... many people who don't have access to Ebony dye woods all the time to mimic its appearance.
Would we want to make a bass with dyed wood? Not really - especially because we have perfectly nice black Ebony available. My quick photo from Feb 11th was to try and ask you about the term veneer you used previously. It wasn't meant to exactly replicate a black color (which showed no grain line, and hence could not illustrate my point).
Since there's a very good chance the dye would bleed into the neighboring Maple, it poses a huge threat to your continued happiness with such a bass. I don't think it's a good idea.
Also, there is no way we would make a 32 scale Small Standard body. It's only available in 30.75 scale. You would need to select a different body shape to have medium scale.
Another way to get the look you seem to want: make the top and back from Ebony, carve the texture (grain pattern) you want in the top and back, and use a combination oil/wax finish to emphasize it. There's always more than one way to do it!
