I think we're talking about different levels of abstraction. Certainly
Unicode does not define any caracters in the terms of how *exactly* they
look like - but they do have an underlying geometrical structure. Or would
you say that the star symbol you get when pressing the, say, "r" key while
using a dingbats font is still, on some abstract level, a letter "r"? And I
don't mean the IPA codepoint (if this is a dodgily made Dingbats font.)

It completely depends on how do you define "alloglyph". "Same Unicode
entity" would be circularish logic, and dependant on the font anyway. "Same
usage", yes, but likewise c with caron, tee-esh digraph, etc; and I think
adding "same origin" to that would giv an answer of "no", tho the diareses /
umlaut precedent suggests that this combo is not the way to go. I see it
coming down to "variations on a basic shape", and at that point my answer is
"no". You can certainly use them as allo*graphs* (representations of the
same sound), but they are no more allo*glyphs* than o-with-umlaut and "oe"

Not too long ago, letters like o-with-umlaut vs. n-with-tilde were also
considered to come from separate alphabets (eg German vs. Spanish), and
arguably they still are. Yet nobody says you cannot use both when devising a
writing system for a language. Also, Japanese, IPA, etc.

Which is probably the main reason the alphabets are considered distinct, tho
I wonder how offen it would come handy. The distinction between different
upper case <> lower case mappings, especially.
