Best ultra fast system I ever used was to use BIAB for the basic arrangement, then mute and replace every single part one by one.

It's quick, avoids the repetitiveness of BIAB and arrangers, but always gives you a full sounding arrangement to play to, which IMO is the key to making the parts YOU play more coherent.

Alternatively, you can MIDI record your arranger, but the important part is to replace EVERY single part with your own playing (or whoever else is helping!).

It can also help to replace the drum track with a nice loop with the 'feel' and groove you want. Then all your 'inside' playing will have the same 'feel'. Then go back, mute the loop, and work on that drum track (or even better, use a MIDI drum kit and a REAL drummer!)...
