Unlikely. "BASIC.SYSTEM" under ProDOS is really little more than a mass 
of glue that sits between ROM Applesoft and the ProDOS MLI, turning the 
various disk-accessing things in BASIC into MLI commands to ProDOS, and 
shuttling any data involved to and from the proper places. 

Integer would need a similar wad of glue on top of moving it around. I 
seem to recall substantial portions (don't take this as gospel - I've 
forgotten how long it's been since I looked at an Integer memory map) of 
ProDOS living in places the RAM-based Integer expects to live, which was 
one of the main reasons it never got "ProDOS-ized". ("main" other than 
the fact that it was pretty much hopelessly out of date long before 
ProDOS came along)
