I think the similarity between Latin combining characters and these
ideographic variations might end there. I don't think there is a
single codepoint version of U&'\+003436' || U&'\+0E0101', unlike é.
This system is for controlling small differences in rendering for the
"same" character[1]. My computer doesn't even show the OP's example
glyphs as different (to my eyes, at least; I can see on a random
picture I found[2] that the one with the e0101 selector is supposed to
have a ... what do you call that ... a tiny gap :-)).
