Abraham, this is a sensible request that I have thought about at times, 
but the context of my question is very different. LilyPond uses 
Fontconfig only to look up glyphs in Emmentaler if the font-encoding is 
'fetaText, for dynamic texts, fingering digits and the like, but for 
most glyphs it uses an entirely different internal mechanism. Here, I am 
concerned with fixing the problem reported at 
which means preventing LilyPond from finding its fonts externally in 
'fetaText (and hopefully there is a way to do this and still make the 
music font searched elsewhere if it's *not* in the datadir). Satisfying 
your request would mean touching a different area, the code that looks 
up music fonts in 'fetaMusic and 'fetaBraces encoding.

By the way, is there already an issue for your request in the LilyPond
