This will most likely kill regular SG. Unless you are teaming I see no reason to play regular anymore. Feel free to argue with me if you don't agree, but there are simply not enough teamed players on any given day to keep regular SG from crashing and giving way to solo SG.
A way to make all this work in an interesting way would be to have Solo SG and Clan SG. Both as they sound... get rid of regular SG and make the role of a Clan more important if a player wants to team. Similar to Counterstrike: Global Offensive in the way were you can brush up on your skills solo, but any sort of competitive game throws in the added strategy of clans.
but idk
