If it would at all interest you, I am in the late stages of producing a Monster Hunter supplement for MONSTER GUTS. It would adapt all the small monsters to fit the "Small Beast" role, as well as adapting any large monsters that grow from a smaller monster. I'm hoping to be able to share it (for free, of course) in the next few weeks.
Due to the massive size of just that content, it's going to be the first in a series that adapts all the monsters from the main MH series to MONSTER GUTS. The first volume won't add wirebugs, slingers, or other things like that, but I'm hoping to add those later.
