From a JEDEC definition:

SSOP: Shrink Small-Outline Package; 0.65-mm lead pitch; 5.3-mm wide body (MO-150; variation AA (8-ld)).

TSSOP: Thin Shrink Small-Outline Package; 0.65-mm lead pitch; 4.4-mm wide body (MO-153; variation AA (8-ld)).

(ignoring 'variation AA', I'd assume).

Your scripts that make the TSSOP footprints can probably make SSOP
footprints with only a change to the body width.
