I would concur with exactly what Peter has stated. Do two schematic symbols
as close to identical for pin locations as is possible. Quite often on a BGA
packaged part, there may be a few additional pins used anyway (additional
gnds or pwrs, right)?

Sincerely,

I'd bite the bullet and do this the obvious, hard way: make a
standard-numbered BGA footprint (A1,A2...) which you can reuse someday for a
different part in the same package,  then make 2 schematic symbols, one for
each pkg.  I'd at least put corresponding pins in the same locs on the 2
symbols so they can be easily 'swapped' in the schematic if necessary...

good luck
