Wait a minute...is this a plot-hole (Austerities of Wind and Main Scenario-related)?

Maybe it is just a voidsent that works the same way primals work, they eat aethers, then turn into crystal and summon monsters to defend themselves with that aether.

Well voidsent as a creature type eat aether by definition, that's one of the primary means by which people like to try and shoot down my theory. Atomos is the only voidsent we've seen behave in this manner though; I don't believe we've seen any other voidsent consume aether just to strengthen and heal themselves. We have seen Garuda and Bahamut do it, but I'm sure someone will find another reason for why that doesn't suggest a link.

To be honest the fact that we have a Bahamut Prime and an Atomos Prime should have raised questions. It's not like the lore team to throw us bones like that and not have them mean something. Most people honestly just seem to try and shut the theory down entirely because of Koji's voidsent statement, even though Koji is well known for being cryptic and giving half truths in an effort to avoid spoilers.

If Atomos isn't a primal then I would like to know why he and Bahamut both have a Prime and what 'Prime' even means in the context of FFXIV's universe. Do other primals have Primes? Can other voidsent have Primes?

I would be more inclined to think this is correct than supposing that the Atomos, a voidsent, gathered followers and became a primal. Just because it has similarities to primals doesn't make it one if it doesn't meet the criteria of worship and aether for summoning. Like you said, it's more likely that Atomos Prime is a type of Atomos that has similarities to a primal, but is still ultimately a voidsent, as Koji said.
