Depends.
I'd expect that
mkdir foo
mv foo foo-1
can be abbreviated
mkdir foo
mv !$ !$-1
i.e. that anything behind "!$" except a colon (as in "!$:t" or "!$:h")
is taken literal.

I'd still prefer the form of "!!:<1" or shorter "!<2" instead of
anything involving further characters after "$".
Additionally, I thought we're talking about picking a single argument
counting from the back, not from ranges of arguments -- which then could
be "!<2-4" or "!<4-2". (I'd allow both forms as both can make sense.)
Kind regards, Axel
