Leia becoming a Jedi Knight actually happens in legends and she nearly reaches the rank of jedi master so I’m sticking with that.

Well, you're right about almost all of these not breaking Canon. Of course, Vader finding out about Luke and Leia would retcon the Original Trilogy, and Leia becoming a Jedi Knight would retcon the Sequel Trilogy.

^well we should at least know how Vader found out about Luke

Vader finding out about the twins, the most viewed episode of the Jeremy Kyle show in the galaxy.

We already got a clone x jedi romance, in legends at least, between a Jedi Knight and Clone Commando. They even conceived a child together.
