Split the difference - do it Archer-style. CGI ships/sets, traditional animated cels with more visible emoting than the originals. Completely redo the sound mix, throw in some TOS music. If you can use the video game stuff to make new 'episodes,' go for it. Then, if it's a success, Season 2 jumps into the TMP era with a new cast of soundalikes who know their way around a recording booth, and it's off to a six-season run.
