I don't think it's a feasible plan, but there's probably some demand for that specific solution--people have friends who play riot games, so they want the ability to play those those specific games without the invasive anti-cheating software.
Doing something like this would probably be illegal if you want to connect to Valorant servers or distribute it, would be easy for Riot to detect and ban users of, and if it worked well it would be a haven for cheaters to ruin Riot games from.
At that point, just make your own game, or easier yet, play another one.
