To Be (Horatio) or Not To Be (Ophelia)...that is the question/brokeback hamlet

since i first studied hamlet in 11th grade ib highers english, i have wanted to play ophelia. i guess playing ophelia is every actress's dream, though, isn't it?
so now that my theater company is doing hamlet (quarto 1) and i have a chance to possibly play the part and fufill my dream, i get an idea about another character in the play and get excited for that. am i shooting myself in the foot? what if this is my only chance to play ophelia?
ok, so here's my idea...what if horatio was a woman? in almost every scene hamlet professes his love for horatio (unlike ophelia). yes, i know it's only supposed to be brotherly love, but they sound like lovers for more than this reason. i envision them as horatio as hamlet's lover he met in college who actually has much more in common with him and ophelia as his high school sweetheart, who stayed at home but he never really broke up with when he went to college in wittemburg.
their first scene together goes roughly like this (in modern english):
hamlet: what are you doing here?
horatio: i came to see your father's funeral.
hamlet: i think not. you came to see my mother's wedding.
horatio: it was a shame that it followed so closely on your father's death.
i can totally imagine a scene before this one like the one in closer where alice is asking jude law's character (dan?) to go to his father's funeral with him while he's shaving. he's telling her no and she simply answers "i love you. why won't you let me go?"
i think it would be interesting to give ophelia a romantic rival. who's to say that one of the reasons she went mad isn't because she walked in on hamlet and horatio? and keeping with this idea, if we don't make horatio a chick, what about making hamlet and he gay lovers? then you could stage a brokeback mountain moment where ophelia walks on, sees them kissing and then walks off in shock. it'd be brilliant...and edgy. or if not edgy, at least a little different.
i'm not sure i've convinced bob (who may be directing the show) of either of these ideas. but i think they're pretty good idea, making horatio, normally a pretty drab character, quite interesting.
so what should i do?
