They could use Speech Synthesis where they use Monty's already recorded voice in earlier episodes to create more speech using technology. It will be quite expensive and time consuming but if they really didn't want a new voice actor they could do it.

I'm just not sure how the RT staff and Monty's family and friends would feel about it.
