Possible new route?

Hi, I'm very new to oot, but I've watched a lot of runs and I wondered if this is possible and if it is, whether it would be faster than the current fastest method. I get that this route will be very difficult to execute, though.

Kokiri Sword, 14-16 Rupees
Pokey Forest Escape/ Fairy Ocarina
Back to Kokiri Forest
24-26 more Rupees (just needs to add up to 40)
Buy Deku Shield
Mido Skip
Enter Deku
2-3-1
Gohma with ISG and stone slab clip
Ganondoor (with Fairy Ocarina)
Void Warp
Collapse
Ganon

This route has no need for the swim in Zora's River, WESS to Kakariko, and obtaining the bottle.
Can someone try this? Thanks  ;D

I don't believe you can use the ocarina in a boss room without setting up Down A for restricted items, the the bottle is required.

Yeah you normally can't use the Ocarina in a boss room, that's why we get a bottle.

Oh ok then.  :(
