Those all look like lots of fun! +1 on the Battleship idea, too! You could also make a dartboard with 1 through 20 randomly distributed on its face for a d20 roll!
As much as I love a full power table-mounted slingshot, perhaps a less powerful setup would make the games more fun to play. You could buy a toy level product or maybe just build your own and use rubber bands. Oh, maybe you could build one out of a wormwood cup holder.
Battleship: Brackets mid-table inside rail, that hold a topper upright as a screen. Yes, you'll need something to screen the vault opening under the topper. Wooden ships with Velcro tops. Catapult style launcher for the Velcro balls.
@@CRAZY-ED maybe crossbows that fire nerf darts... Also, this is a biggie you might pitch down the line after you've gone through your current ideas. How popular is Beyblade these days? Could potentially be a collaborative Kickstarter with Hasbro. Wyrmwood table sized arena with custom rail-mounted launchers that drop the beyblades into the arena. Seems like a perfect idea for the Hex tables.
How about a catapult form factor? You could put the playfield within the table space and then just install a backstop, and not risk dented walls or broken windows.
