The OP's plan is to use one font for the BMP, one font for the SMP, and one font for the rest. However, the BMP font Code2000, which only goes, incompletely, up to Unicode 5.2, uses 63,546 glyphs, which is very close to the limit of 65,535. There is the slight margin that it included a few small scripts with standardised (ConScript Unicode Registry) PUA allocations. Richard.
