Is this too harsh of revenge on a guy?

Well a few months ago, a guy and i were talking and we actually got super close to dating until he left me for another girl he claimed he didnt like. Of course like any girl i felt like an idiot and extremely embarassed i got played by a player. My lesson was learned. So, now (a few girls later) he starts talking to me again. He apologized for screwing around on me and ive heard that stories a million times. So tomorrow he wants to hang and i got the idea to play him in his own game since i think he wants to just get in my pants, again. So its alone time and i figured we'd talk, and give him what he wants (strictly kissing) then, id have my sister call, prentending to be another boy, and id walk out on him explicitly saying this is how you learn what being played feels like. Too harsh? Too bold? Or is it a good stand for all the innocent girls who've been in my shoes? Please tell me what you think.
