Yes, it would. I do it the other way around for some TV shows that aren't in the UK. You would need another iTunes account though, one with a UK address etc, just google a hotel in the uk and use theirs. Then switch to that account, redeem your itunes voucher and spend as required. You will need to authorise your computer as per normal to play the songs. I believe the issue would be getting the itunes voucher. You can buy them off ebay, but you need to be careful, a number of folk have reported issues whereby the vouchers have been purchased with cloned credit cards etc.
