I actually found DOC in some ways similar to mescaline, they're very different, but there were similarities... Though DOC is longer lasting, less empathogenic, euphoric, and possibly even less "spiritual", "magical", whatever adjective you choose to describe the serene feeling of mescaline, but with the advantage of less nausea and stronger visuals. This is just my experience though. DOC is a really deep experience for alot of people, so don't take my word for it.
You've already ruled out 2c's, so out goes the 2c-c suggestion... though I wouldn't exactly consider it a "mescaline replacement". It's always brought up time and time again that searching for replacements only lead to disappointment, but it's true really. Even the mescaline analogs are said to be unique. I've only tried Allylescaline and Escaline, both were kinda similar but very different at the same time.
Personally, AL was super jittery, nauseating, and filled with body temperature fluctuations both times I tried it. Once you get past the rough few hours it was okay I guess, but it was no mescaline that's for sure. The visuals and headspace just weren't there, went well with 4-subs and a few other tryptamines but I'll have no troubles passing on it should it ever be offered to me.
Escaline was better, but wasn't a full blown psychedelic experience... on it's own at least, when unknowingly dosed a few mgs of DOC before hand you would think Escaline was the lost treasure, but that's another story 8). Visuals were closer to 2c-i, body high was definitely mescaline-esque, and the bodyload was honestly a lot better than I thought it would be. No nausea, minimal tremors, and a comfortable stimulation. Escaline lasts about 8 hours ime. Once again, I can only speak for myself. I'm gonna go ahead and agree that you should just purchase mescaline for a mescaline experience.
