I don't think you'll be shocked by MKK, but I'd still be cautious, only because I don't think that liking BaV or Joy is any indicator that you'll like how MKK smells.
It may be my nose, but MKK isn't the slightest bit dirty to me - it's just a very-present musk that I find a bit fuzzy and raspy in my throat. I know I'm not selling it, but I actually do own it and like it very much.
I do agree with Cacio about Kiehl's (the EdP, not the oil). It is dirty, and you should have no problem with it given what you like. But aside from that, the smell is definitely very different from MKK, so keep that in mind. I'd certainly sample it first!
