If I change my iTunes account to the UK (from US) can I bring my UK purchases into my iTunes library?

So I live in the US, but I want content only available in the iTunes UK Store. I know I would have to change my Apple Astor’s account settings to a new country (UK) and provide a valid UK credit card and address but can I then merge all items together into my iTunes library. I can’t stand these blasted country distribution restrictions! If BBC uses local UK contributions to produce their content, why not just charge a fee for non-UK residents To offset the cost? (Out of state tuition, anyone?)
