In relation to how I will handle continuity (Trisell Chronos)

After sufficient time in this wiki, I've decided that my characters are too completed (at least a good amount of them) in their main continuity to really get much in terms of new content. I'm not going to get rid of their main canon as that's what I plan to actually develop into stories and such, but for this wiki, I'll be creating more base versions of each character that will include their main aspects, but leave out events and characters they've been affected by to varying extents such as romantic interests, rivals, enemies, places they've gone, adventures had.

I will be referring to these versions as

"IAR CONTINUITY"s or "In Another Roleplay Continuity".
Just in case anyone's confused, here's an example.

A character of mine named "Dave Hyatt" has a backstory where he was taken from his world into the main multiverse and ended up in a place called "Mobius Academy". There he met some friends like Talia Reephs and Kyle Waktini, which developed him into a successful guitarist, best friend, and eventual husband (spoiler alert).

In Dave's IAR CONTINUITY he still was taken from his world and ended up in Mobius Academy, but he wouldn't have known Talia or Kyle, and he isn't a successful guitarist. He is open to new romantic interests, life-careers, and friendships.

These IAR CONTINUITIES will not be in effect when using the WHAT-HAPPENS-NEXT Plot roleplays (of which I have posted three you can find here .  These roleplays are completely within the main canon and will only involve the canon version of my characters.

What I haven't decided on yet is if I will be making these as add-ons to current profiles or make them full-out separate profiles on their own. Thoughts?
