I did something similar the other day using a free virtual credit card service I frequently use. In my case, I am US-based and wanted to buy a digital product that could only be purchased using UK-registered payment options, so I created a virtual credit card with a fake UK billing address (this is explicitly stated as permissible by the virtual credit card service I used) and bypassed the restriction; my bank automatically converted from US Dollars to British Pounds as part of the transaction. You might be able to do something similar if you use a virtual credit card service. (Interestingly enough I could not associate the virtual credit card with PayPal because PayPal would only let me enter US billing info, so I had to pay directly - still worked!!!)
