I just had a pup made at UGD that has an aged A2, however it's in an overwound 9.2k bridge pickup, so I can't really compare it too much. Compared to my 8.43 standard APH (b) this pickup has more punch and articulation, but again I think it's because of the overwind.
The tones with an aged A2 are supposed to be just slightly rounder and warmer on all frequencies as compared to standard guass mags. Do you have a standard A2? You could just do a quick swap.
