one of both events should have more or less participants. or could riot change the format. can't be so similar imo.
Riot formats are total garbage, you may hope for more stacked tournaments with two broadcasts, full round robins, swiss systems and double elims, but it won't happen, the company is simply braindead.
Just look at their Worlds format. Some teams travel all around the world to play 6 Bo1s and go home. Isn't it dumb?
