That would be really nice, and especially useful for the time being 
while XeTeX does not support one-out-of-many GSUB features.

When I build OpenType fonts, I generally try to make sure that there is 
a certain redundancy in how applications can access various glyphs 
through OTL features. For example, I always map a glyph such as "b.3" as 
the 3rd variant within the "salt" feature as well as a simple variant 
within the "ss03" feature etc. Unfortunately, each font developer has 
his/her own conventions in doing this.
