Realistically is they were
going to try and revive TNG in some form, a CGI cartoon ala Clone Wars might be the go? You could hire the entire cast then without worrying about scheduling conflicts or concerns about androids getting a little too pudgy around the middle.
Indeed, such a scenario could even take place during
the TNG television series, rather than necessarily having to be a post-Nemesis universe.
It would be a creatively berefit idea, but it'd certainly tickle the nostalgia bone if that's what they were aiming to do.
