I think we've been pretty good about not oppressing you because of you of your youth, Altar, by and large, but I will say this:
At some point it will occur to you that what you want -- and your reasons for wanting it -- won't need to vetted by the court of public opinion, because you will know yourself well enough to walk your own path.
That said - I'm not personally a fan of the red exotic woods, so an attempted body/neck match seems like too much of a thing I don't like much even in small doses. If it's what you want, though, it is, by definition the right answer to the question of "is this a good idea?" The input that's worth seeking at that point is about how well various bits and pieces function, whether they are likely to provide value (once you define what's valuable to you), and so on.
I also agree with Joseph that the different chunks of padauk will likely age and discolor differently from one another, so you could end up with a red guitar with a brown neck, or vice versa, or two different shades of brown.
