A comic can be done with 1-3 people, artist and 1 or 2 writers (maybe 1 funny person and 1 science person at most, can also be one person who can write well for both sides of it).

A video series would be easier if it was live action than animation, but if you go a dual route of monetizing and publishing on non steem-related platforms in addition to uploading to dtube then the costs can probably be absorbed fairly quickly.

I myself would rather enjoy seeing a steemstem branded video series that can rival the quality of the other popular shows, it would create a constant source of publicity for the platform and for the group, and it could be (at least for now, until they try their funny business if it gets popular) above the realm of corporate interference regarding how topics are discussed. It's fairly annoying to see that every other video, or every video, on youtube is actually just an advertisement paid for by a certain company that wants you to think a certain way about some product of theirs, even in science videos.
