Not really sure what you are asking - maybe you can be less
hypothetical?

A shaper module's whole purpose in life is to map Unicode character
sequences to pairs of glyphs from particular fonts.

If you have a font, however, that has a incorrect character map
that assigns ligature glyphs to random ASCII characters, you 
will have great difficulty getting that to work within the 
framework of the fontconfig-based backends for Pango.
