Obviously, the setup will require a little tweaking — the player characters are currently in December 1610 Prague while BTAM takes place in October 1631 near Würzburg — and Unknown Armies's brand of cosmic horror isn't quite compatible with Lamentations of the Flame Princess's brand of cosmic horror. ("You did it" versus "The Old Ones were, the Old Ones are, and the Old Ones shall be.") That having been said, though, there are enough parallels that I decided to make the jump. (While some of the stuff on Goblin Hill isn't quite Unknown Armies, the whole Karlstadt-overtaken-by-sorcerers-and-Gustavus-Adolphus-isn't-happy-about-it plot is incredibly Unknown Armies. "Sleeping Tiger" and all that.)
Assuming all goes according to plan, I'll probably post my conversion notes on here at some point. To tide you over, have a pair of early modern Icelandic necropants, courtesy of that guy at Warpstone Pile.
It will also probably be a good opportunity for a review for Better Than Any Man, because I've been lax with my LotFP reviews lately.
