tarrey town% would be really cool and interesting, what do you guys think?

Yeah sounds good.

I wonder what goals and what timing endpoint you have in mind, and whether you would run it

Well, the goal is to build tarry town as the name implies I would say about 1 and a half to 2 hours fastest time, taking into account getting all the characters. I personally might be interested in running it. But im no professional so my times are probably off Also this is not my post its santibo's

one thing to consider though, is that i get the impression that most 100% runners dont like "From the Ground Up"

They spread the quest out across the entire route

Thats my point, they don't like the fact that the whole run revolves around the quest

It would be interesting tho.
