My face for smashing pumpkins concert?

Alright so im going to the smashing pumpkins concert tonight. I wanted to be a little more creative and use some liquid eyeliner on my face and draw my face into a jack o lantern kinda, with the mouth and the triangle around the eyes. 1st question is, is it ok to use liquid eyeliner on the face, lips, and stuff. 2nd question is would you think this is cool? I wouldnt want to show up and feel like an outcast. I mean im going to a smashing pumpkins concert so why not draw the face of a pumpkin on my face? :D by the way im a guy :P
