Here are all improvements found so far...
Luigi:
As /u/bonfire10 pointed out, Luigi is able to fall off the ledge, perfect mash down b, misfire right, then up B to the ledge. https://gfycat.com/BadWideeyedBarb. This gets him out of that area but he gets stuck in the pit right here, https://i.imgur.com/QPFEN9C.png. Because of this he stays in the same spot.
Ness:
Ness can actually make it out of the first area. When I played I just assumed that the PK Thunder would just fizzle upon hitting the platform but as +Andrew Ricklefs pointed out, It doesn't, and I am able to make it out of the first zone. He can also make it to the next area, and pass Luigi on the tier list
/u/Z1mb0bw4y has provided a video - https://youtu.be/_3dZc7LzF9M
Dr. Mario:
Dr. Mario, Mario, Marth, and Roy can use a tech to extend their up b's slightly. I couldn't find much information on this tech other than this blog post - http://ikneedata.com/ and like one other smashboard post. I used this tech on Doc, this was as far as I could make it. - https://gfycat.com/BeneficialGlossyGilamonster While he is unable to make it to the platform he does gain a bit of height, sending him to the top of F tier. This is supposedly possible with Marth and Roy but I was unable to get this to happen. Mario doesn't get any benefits from this tech.
Mario:
Mario can make it! Thanks to the help of @|3rian on ssbwiki's discord, Mario is now able to walljump on the last area, putting him into A tier. Heres a gif of it - https://gfycat.com/LinearVigorousHalcyon
The explanation for this is pretty complicated, so I'll cover it in my next video, which will show off all improvements listed here. He finishes at 17.21, putting him in the middle of Falcon and Ice Climbers.
Kirby:
Using down B before up B gives him a bit of height, boosting him up to 2nd place on F tier.
FAQ:
Q: Can't Link do the boomerang superjump as well?
A: Yes he can, but due to him throwing his boomerang faster and not being able to angle it as well, he can't use it on the Brinstar Escape Shaft.
Q: How did you do Peach's run?
A: I used the 20xx training pack to guarentee a bomb pull everytime, but if I hadn't, that Peach run would have a 0.0000000000000000000812234494% chance in happening. If I did the math correctly.
and Sheik did not jump. Thats just her aerial up b.
