Altra has the Superior and King Mtn, both of which have less cushioning and arch support than the Lone Peaks. The Superior 6 is my go-to right now. I train almost exclusively in Xero Prios. I also run in Mesa Trail IIs with a rock plate.
I know what you mean by the old NB Minimus line. I LOVED my original minimus trail. They were the perfect shoe IMHO.
Currently I use the Altra Trail Superior 6. But I think if you wanted to be as minimal as the old NB Minimus then perhaps something from VivoBarefoot like the Primus Trail FG 3.5. Xero shoes has some pretty packable ones as well
Altra uses 3 different foot shapes, not all their models use the same shape. https://www.altrarunning.com/en-us/about-us/footshape.html. I started off w/ the Altra Lone Peaks then didn't understand why i didn't like their Superiors as much. Turns out i only like their shoes w/ original footshape (LPs, Timp).
