"The creation of new mini types is reserved for either a) the creator of the OFU in that continuum, or b) if there is no OFU, the first person to write about them in a mission to that continuum. The reason for this is that, while it's fun to dream up mini types, it isn't fair to the people actually writing in a new continuum if the perks of doing so are gone when they get there."

Speculation is of course fine (albeit a bit pointless, other than as a mental exercise) but there's no way to suggest a type of minis. You either write the OFU or the first mission for that canon to feature a mini, or you don't.
