I don't know about the stick.
To be honest, if you go for sick-looking girls (rescues) you will probably need to QT them for longer than two weeks, and you'll obviously also need to have whatever meds necessary to heal them first.. Some rescues just cannot be put into a sorority, as some of them end up with permanent physical damage from injury and whatnot that would affect their ability to swim and function properly. Sorority girls need to be in good shape before being released because you WILL see chasing, nipping, tail slapping, flaring, and possible fin and scale damage. If you've got any weaker girls that are not as quick of swimmers, they might get injured.
Another thing is, 4 girls is bare minimum and you'd do best with 6-7 in a ten gallon to spread out that aggression. I've got 6 girls and have still seen some fighting and fin damage. A ten gallon is also bare minimum and I do not think it would be a good idea to do a sorority in a 10 with other fish. A 10 would work better with some schooling fish and a male Betta. I would have at least a 20 before adding other fish in with a sorority unless it were perhaps snails or shrimp, but your girls might attack those.
I'm not saying that you CAN'T do that (I'm also not sure if the bioload would be too high) but I wouldn't personally do it and I do advise against it.
I hope that helps.
Edit: I forgot to mention that 2 weeks for QTing is recommended for even healthy looking girls. Sick ones are a different story. If you want a bottom feeder, I would go for snails such as nerites. I would make sure your tank is cycled first or has lots of live plants. Then you won't have to worry as much about getting a bottom feeder and nerites are good at cleaning up algae.
