Prime Only Warframe

Okay, so while I am fully aware the chances of what I'm about to say are practically zero, its just a random thought that I wanted to talk about. So as we know all Primes are the original versions of a frame, weapon etc (in most cases). And we have a few weapons that only show up as Prime versions, no base version to compare it to or obtain. So, what if in a future update (not a big one but one of the mini ones) they add a warframe that is only a Prime, no base versions were made in batches, but just an original Prime frame that was one of a kind and was either lost or destroyed during the night of the naga drums? It would be a great way to give us extra story and lore for that night while introducing a fun twist on their warframes. Like the update could have a normal frame and weapons that you get by completing one part of the quest or new mission that gets introduced, and then the Prime only frame can be gained via the quest or maybe even via Varzia, make her more than just a prime vendor and add her to a quest area, maybe a research ship on Lua or a newly discovered orokin structure in the void. I'd love to know other peoples thoughts on this random (definitely sleep deprived) idea I had
