Most folks will just laugh at this idea, but for TG fetishists like ourselves, the possibilities are endless.

Personally, if I were in charge of the series (I'm not), I'd have Harrison Ford fall into a pool where Amazon warrior women like to bathe, and morph into Megan Fox. Sequel/reboot with TG appeal! What's not to love?
