Not trying to blow smoke but I've wondered it as well. What are you using Hoecht for? Why was he a priority signing when his calling card is positional flexibility?
At the time I dug up this article about a 4-3 under
https://weeklyspiral.com/2021/10/04/4-3-under/#google_vignette
Basically the advantge is that you'd give the 3 tech (Oliver, Carter, Sanders) a cleaner shot at penetration by shifting the attack to the weakside but the things you need:
-a 3 tech who can penetrate
-a weakside LB who you have to trust as play flows to them (Milano)
-a strongside LB who effectively plays as a 5th down lineman but who can fall back into coverage (Hoecht) that I would assume would be the 9 tech DE on nickel packages or swap to single S with Taron out playing
Is this going to happen? I have no idea. Do think it would be reasonable to at least have that as a subpackage for bringing pressure against, say, a run heavy team *cough Ravens* while keeping coverage options open? I'd say so. Would it explain chasing Hoecht and ignoring Safety (if you plan on just using 1 a lot of the time)? To my deluded brain it just might.
