Good idea!
Maybe time signature and pattern length alterations could be used to create fills?

asked for this too, I would kiss loads of smelly feet for this 
the idea of defining “inner loops” in patterns is rad.
in (my) best world I could do it live as described and as a feature for scene/perf mode: automate structural params like pattern length and signature and have different “fills” available via scene or even crazier perf mode. a “first step” param would be very helpful of course
