ok, i called johnson hardware. apparently full-access bi-fold on one side and regular bi-fold on a track for the other does not work. the doors won't match because you need 1 in of clearance for the regular bi-fold on a track, and the other door only needs like 1/2" so it'll look funny.
BUT they did say dividing 60" into 3 doors of 20" each, one side had 2 doors in a full-access bi-fold, the other side has 1 door hung w/hinges should work.
i got one quote from a custom shutter place at $880 for finished doors, trim, installation. i'm waiting on another quote.
i know...nuts to spend so much on closet doors, but what must be done must be done.
