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.)
