Dynamic Queue Compromise?

Just finished taking a shower and I thought I'd ask a quick question.

Why not just use Dynamic queue for solo, dynamic, and 5's mmr?

What I mean by this is why not make it so that we have three types of mmr/rankings for dynamic queue?

Example: Solo Rank - 10 games by yourself Dynamic Rank - 10 games with 2-4 people Fives Rank - 10 games with a 5 man premade

So depending on how many people you have in your group (whether it be by yourself or with 4 other people) you'd get placed in a match using the mmr for that rank.

So even if you get boosted to diamond via dynamic or 5's team, you could still be considered a bronze or silver on your solo rank if you ever decide to solo it out after your "friends" dump you for being "bad".

I'm aware this won't solve most if not any problems with dynamic queue as it is right now, but I thought this may be a nice compromise.

I dunno. Would this be a viable solution? Could it be improved? Thoughts? Suggestions?
