I had this idea in the back of my head and I haven't really organized it that well but what if there was a "pro league" where high im-> top invite players could play by paying a small entry fee (say 10 USD) and play some quality pugs to win some prizes (such as hardware or money from sponsors or a fraction of the entry fees) based off of some sort of metric just like in FaceIt's FPL for CSGO.
More importantly I think this would establish some sort of Rank S system and would attract a lot of viewers on twitch ( I assume it would since whenever NA CS players are playing Rank S, they get so much more views compared to anyone else) and I also gotta say that watching top level PUGs is extremely entertaining from a casual/amateur perspective and would grow the competitive scene a lot more.
EDIT: not saying this should or could happen; but theoretically would be very cool
EDIT #2: Maybe the pro league could be played off a pugchamp client, but that would unfortunately take a lot of dev time with little to no profit or reward to the devs
