Alright, after messing around with the Water Temple OoB glitch for a while and doing other stuff, I can conclude that:
You know that room that has the spikes to prevent you from climbing up and has a hookshot target on the other side that requires the longshot, which also leads to the boss key? Well, with the OoB glitch and the water all the way up you can almost
land on the other side of the spikes, in fact you an actually land in the water and swim just underneath the floor past the spikes, but you can't get up. (Also, that route requires 2 keys to get to the boss key.) Theoretically, if we had the hoverboots we would be able to skip the longshot ONLY IF I could get that clip past the spikes to work (spoiler: I can't). Honestly, this is physically hurting me to do. ugh.
Aaanyway, for Forest we can just grab the bow and TSC into unloaded basment to the boss room.
Fire can techinicaly be done with first, with only 6 hearts, but at least 7 would be prefered.
Spirit can literally be done on a whim, as it doesn't require anything but the hookshot and we already have Requim of Spirit.
Shadow early is being considered now
