Need a hack

I want users to be able to create events on the main site and sell tickets to those events. The problem is that in the plugin's settings in the PayPal email address I use my email address. Means that when users will buy tickets the money will go to my PayPal account.
My question is, is there a way to modify the plugin in a way that when one wants to buy ticket he will be sent to the PayPal account of the user that created the event? I can maybe use the email address from the user profile or add another field for PayPal account email.
