I don't think Hogsmeade would survive with a dead end. Especially with the show on Hogwarts Castle, it creates huge bottlenecks throughout the land with people wanting to get up close to see the show. The only real way in during that time is through the Hogmeade arch and the only real way out when it gets super packed can be the JP bridge unless you want to deal with going against the masses.
Yeah, I agree you can't have a total dead end at hogsmeade for crowd control reasons, but you could remove the JP bridge and instead have a pathway that snakes behind the 3 broomsticks similar to Hollywoods path and drops you off at the Jurassic Park waterfront area?
