Why not tame them first, then find them a home?
It is usually impossible to tame a feral adult cat. Even feral kittens 10-12 weeks of age can be very difficult to domesticate. It requires a sincere commitment of a few hours per day, for months or perhaps years for older kittens or young adults.
Even if a feral is predisposed to socialization, a feral cat tends to bond with their primary caregiver. Once placed in another home, the cat will revert to a feral state, making them unadoptable. Do not attempt to socialize a feral cat unless you plan to keep him/her.
Forgotten Felines of Sonoma County does an outstanding job at explaining what is involved and raises issues to consider.
