That would be fine. There are quite often on various lists questions
about how to "correct" a font, e.g. adjust kerning, or add a missing
glyph etc and a interface for "virtual lua fonts" would make such
corrections much easier.
The example in the documentation uses as base font cmr10 and loads
it with f = font.read_tfm('cmr10',size). How should one load the
real font when it is an otf?

If you adapt the context files I can make some tests by exchanging
the luaotfload files and tell Khaled the results.
