Awesome list Levitas!!!
A few suggestions, why not do stage related things? Like how Lucas can recover obscene amounts of health on Corneria (if it's legal)? Just hop down there when the main gun is charging, throw out PSI magnet, and recover, and you can zap jump to get back on the ship, or use your second jump and PKT2 onto the ledge or the main gun. I usually go for the main gun, it's safer, in the case of your opponent trying to edgeguard you. From the main gun, you only need your two jumps to get back on the ship. Also, you can jump on top of an Arwing/Wolfen and keep PSI magnet out. It's risky, but you can recover a lot.
Or, on Luigi's Mansion, where it's legal, you can discuss dtilt lock setups from uptilt and downthrow and moves like that.
