This seems unlikely.  If you have the tech to create non-interfertile
branches of humanity, you likely also have the tech to create offspring for
any given set of individuals from said non-interfertile branches.

I once wrote some sci-fi (the intended publisher rejected it) in a
space-opera-ish setting where humans created catgirls (homo sapiens with
mostly aesthetic feline features, initial generations created via cloning
with a heavy bias toward females as part of the attempted disguise) in an
effort to present some "non-humans" to aliens who had put restrictions on
human activity (basically, get the catgirls to swipe, barter for, or
otherwise obtain certain alien tech that the aliens had forbidden giving to
humans until the humans could invent it on their own).  The fact that they
could crossbreed with humans was among the factors cited by the aliens in
classifying them as human and thus subject to the same restrictions.  (Then
said creators ran into a case of, "just because you made them, does not
necessarily mean they're loyal to you.")
