I don't know any possibility for shell aliasing arguments.
The aliasing is a shell input feature.
/usr/bin/sudo and /bin/sh -c "X" executes programs without any input parsing.
I think it would be a security leak if any replacement like aliasing
would be done in such executions.

You can force sudo to accept /bin/rm only with "-i" or "-f" argument.
Read for this "man 5 sudoers" and use visudo.
