What is Best H/H Team Build for UW?

I want to do the Underworld, but only with H/H. What is the best build for this? A miracle, since henchies are not available for UW. Considering that people have been asking for a two-person/six-hero build that can do UW and have gone unsatisfied so far, there isn't much hope of you doing it solo even with three borrowed heroes in place of the henchies.

I have done substantial parts of UW with a discord team and three borrowed heroes. However, this was done strictly to explore the place. It simply isn't possible to do many of the quests that way, beyond Chamber and Vale. The Plains are a particularly difficult area because of all the hex removal, so the borrowed heroes were more of a balanced group who carried most of the load there.

why bring a team of heroes when it is possible to solo farm planes for ectos? I didn't know it was still possible after the recent update when SF was nerfed.
