[Homebrew] Adjusting sharpshooter for throwing

For the most part I've intended on using the sharpshooter feat, but would prefer to adjust it slightly to make throwing a viable fighting style.

The parts that it would make sense to keep would be the range and cover ignoring properties of sharpshooter (These already apply to thrown weapons anyways, and to some extent are necessary to make thrown viable), but I would like to replace the -5/+10 ability. I'm trying to think of ideas that mechanically would be fitting to a throwing weapon feat but I've been coming up with blanks, and searching online hasn't found me anything quite like what I'm looking for (With most being overpowered as hell).
