   Per bash manual:
   -----8<-----
   ALIASES
   ...
   Aliases are expanded when a function definition is read, not when the
   function is executed, because a function definition is itself a
   command. As a
   consequence, aliases defined in a function are not available until
   after that
   function is executed. To be safe, always put alias definitions on a
   separate
   line, and do not use alias in compound commands.

   I might be complicating this too much.  Instead I can use shell vars

GREP='/bin/grep'
