Hi Sergino, I see your point sorry about missing it myself! Still, RB will do some amazing things. Obviously some styles simply won't mix together no matter how "creative" you try to be but others will mix very well together.
What you're asking for could be very nice and certainly the more options the better but, the problem with adding more instruments to a given style is we're asking the authors of the style to come up with more and more complex backing tracks without knowing anything about the melody lines in a given tune. This would be especially true with big band or other large ensembles. There, you have different point/counterpoint lines going on based on what are usually several themes in the piece. To try to come up with a 20 piece brass/woodwind backing arrangement without knowing exactly what those lines are ahead of time would create a useless mishmash of sound imho. Just look at one for example, Chatanooga Choo Choo. The melody/lyric goes "Pardon me boy, is that the Chatanooga Choo Choo?" and the band goes Waa, Waa with the horns. How could that possibly be created by a generic style without knowing the timing of the melody? It would be very cool if we could enter the melody phrasing and somehow a style would create the parts around it. Never say never but I think we're a long ways from that. On the other hand if such a style could be used to simply create a whole new song and we write the melody later, that could be interesting.
