User blog:WeissSchnee/A Question About Interaction

So, I had a question about OC interaction with Canon characters.

A major part of Viola's back story was the fact that she met Roman through Grayson, and that he sent her to Beacon to pass him information and to eventually assist he and his men when they attempted a Dust heist at Beacon.

Now, I know that is making a lot of assumptions (a Dust heist of Beacon kind of became my head canon after seeing Beacon circled on Roman's map) about what is going to happen in the future of RWBY, and that possibly that heist will never happen, but I was wondering if it was possible to include an alternate back story on her profile, perhaps under a Non Canon Background heading?

If this isn't acceptable, I understand. No harm in asking, right?
