Derby name illustration

My daughter is a (badass) roller derby skater. Each skater has their own derby name that is part of their “on skate personality”. Her’s is “Loose Cannon” and based on that name I would like to get a black and white illustration of a cannon in connection with roller derby. That could be something like a cannon on skates with a cannonball with a helmet or anything along those lines that someone can but into an illustration. This will go. On a black as well as white scrimmage shirt and therefore needs to be all black and all white version. Attached are some ideas to start a design (not my designs), but words do not have to be included in the final illustration.
