Rule of Cool isn't so much a break as a do not meet a criteria.

See, RoC is when a person willingly suspends their disbelief in something crazy because it looks cool. The weapons in RWBY, from our perspective, are more or less fueled by RoC, although they do have perfectly justifiable mechanical components, they are also completely insane.

The sickle and sword style is different, definitely, and i can't think of a reason it wouldn't work.

Same with sword and pistol.
