I'm writing a script which is being put on this august. Its called 'shakespizzle' and is a modern day version of romeo and juliet where montagues are chavs and capulets are goths.
I'm not sure where you could find a whole script, but maybe making the sword fight in act 3 scene 1 a gun fight, or a how many times have you been arrested, and whoever has the most wins. Sorry I couldn't help.
