It seems a bit sad you would switch to using a blowgun because it does 1 damage. How could you justify it doing 1000% more damage because of Sharpshooter? When you consider the net does no damage, does 1 measly little point really justify the feat boost ability?
I would rather try to work with my player to bring about the concept they want instead of worrying so much about the rules, but that is me.
If I had a rogue using a net to sneak attack with, the damage can be warranted by reasons I've already outlined, but if that doesn't work for your game, I hope you find something that does.
I don't feel it would be against* a home game. I simply wanted to investigate how a net might be useful.
*Though, upon further review, I could possibly see a game balance ruling against it...
1) Rogue throws Net for sneak attack damage
2) Opponent is restrained and needs to take an action to attempt getting out
3) Bonus action to deft hands another net
4) start over at #1
hmm...
This just hit me as I was typing this, but perhaps a net and shield combo could be interesting.
1) Throw net
2) restrained opponenet
3) shield master bonus to knock the opponent prone
4) speed 0 opponent can't stand up
