They usually want it cleared and voted on prior to the seed run beginning. There are folks around here who accept seeds too distribute to the community on the growers behalf though!
You can try to ask them in the Seed Run Co-op Voting thread, but don’t get your hopes up, since the run is complete already. Additionally the Co-op approves discontinued lines, so there might also be concern since CS still sells it (I get the irony there, since CS is reproducing other breeders genetics🤪).
Here you go, you can try your luck!
Just make sure you read the post where they say how to submit it, if you decide to try.
