Yes, and I prefer not to replace one thing that's dumb but at least has some tradition behind it with another thing that's dumb and has never been a thing in soccer (unless you're talking about playing with mini goals that you see in some youth soccer setups, in which case I'm game but that's not going to speed things up any).Penalties are already a different sport.
No goalkeepers is a terrible idea unless you like the idea of each team camping three defenders on the goal line with their hands clasped behind their backs and trying to rocket shots in from far away and hoping to either get it past them, win a corner kick, or get a handball penalty (in which case what happens? do you shoot into an empty goal?). 30 minutes of that? I'll take the PKs, as much as I don't like them.
