Not many Uchiha awaken MS from what we already knew in manga
Thats mean 3 tomoe sharingan implanted into other 3 tomoe sharingan wont granted any new power.
That is definitely true, but Itachi did mention there were a lot more in the past while Izanami was created (or so the legend says). I would like to think a few from that era could have survived and would have had the opportunity to try this.
That was filler.
I'm not referencing that, but alas I forgot that MS is not needed for Izanagi or Izanami. It can be done with any sharingan.
I'm pretty sure filler is canon whether people like it or not, otherwise the term "filler" would be a misnomer. Besides even if those uchiha had MS they showed no particular special abilities or maybe they were not in range to use it.
Izanagi needs Senju/Hashirama chakra to work though. It's how Danzo, Obito and Madara were able to use the technique.
Although it does beg the question as to why Izanami was created to punish those who abuse Izanagi. Unless, you know, Izanami was just an asspull by Kishi and essentially functions as the "beat DSM Kabuto no Jutsu".

The Uchiha just started being medics
But we know both Obito and Madara have done the transplant procedure no problem and they're not medics.

Do you a medic or has anything related to madic in real life?
Eh, I tried it, I wasn't passionate enough
