To me, the 1st step before thinking about anything else is the unmaking of the 2min meta as it is today.

THEN job uniqueness and complexity, innovative encounters, etc, can be thought of.

There's little that can be done for mid/hardcore content when everything needs to gravitate around 2min burst alignment only. No wonder why Bozja's fights and Lost Actions felt more interesting, because you were tooling around with a lot of things that were not a strict 2min burst window.
