Insane Asylum Challenge- Modified Sims 3 Challenge

I am thinking of having this Challenge be thrown into my story I am writting. The story I am writing is called True Love. The reason I am contacting you is I want to use the girl from my story that going be forced into this Mental hospital but she going be a teen when this happens. Would it be okay if I use the same challenge rules but let her be a teen and the other will be adults and young adults. Can change it up for me and story with your okay @rinnyroo ?
