i have an idea with that sandman that uses a snowball...make it a whole new item
the snowball can't be retrieved, but regenerates twice as fast as the baseball
and friendlies who are on fire can be put out with a quick melee (if you have the snowball) or hit them with the snowball
and finally, the snowball won't stun, it will instead act like a jarate and cause enemies to take mini-crits for a short time
the name: i'm not creative enough to think of one
