You can add additional instruments to any BIAB style regardless of the type of style it is. BIAB (Band in a Box) has a lot of variety and choices of pianos to play solos for your songs. There are MIDI, MIDI SuperTracks and RealTracks. You are also correct that you can also have someone play a live recorded instrument into BIAB to mix with the BIAB backing tracks. Also, someone can pre-record audio and that can be used as well.

I can't completely answer your question whether you need to create space (add additional bars) for your piano soloist or just need to add an additional piano instrument to your style of backing track instruments. Regardless, whichever you may need, it's possible to do both in BIAB.
