Audio exists for ALL missing episodes, so hiring a cast to re-enact them would cost far more than farming out to a small group of animators.
However, if you’ve still got a craving for Bradley’s First Doctor. There’s this to look forward to from Big Finish:
It looks on par with previous animations. I doubt the Beeb is ever going to fund some full blown CGI recreation of missing footage. That might get into creepy territory though.
I would never advocate for CG recreations. But it would be nice to hire this team again. Their efforts were a lot more dynamic than the recreations that came after.
