GSUB alone could be used by mapping to a precomposed glyph. I'm not sure
what features would be needed to implement this, though, and getting the
feature support for this (either for GPOS or GSUB or both) by implementers
isn't highly likely, I don't think.

I also thought of this. Question: what's the disadvantage of the dot not
being a combining character?

Yes, though it does depend upon font developers supporting a
language-specific behaviour. My guess is that it would be easier to
convince font developers to support a new above-right combining mark than a
language-specific treatment of U+0307 (I may be wrong, though).
