The only people who would want to be dolls are the criminally insane - but who retain enough grip on reality to realize they are thoroughly dysfunctional and have zero chance that their condition will improve. (Their backstory can include thorough and futile medical treatment that would arrive at this conclusion. Maybe the Dollhouse can provide this treatment and extend the offer of doll-hood only to those who legitimately cannot be cured.)
For people like that, negation of the self is the only good option. Doll-hood should be the absolute last resort before suicide.
Also, the lead character should be some scruffy, big hulk of a guy - think Gerard Butler - so that there will be no nauseating tendency to treat the lead character as a poor widdle victimized girl. Nobody's going to shed tears over Gerard Butler who used to be a serial killer who did stuff that would make Quentin Tarantino violently ill, before his identity was wiped clean, but we might find it interesting to see he can maintain doll-hood and hold that other nasty guy at bay.
So, in other words, you want Alpha to be the star of the show.
