Convert foreign keyboard

[vaio-fx]

I will be selling my desktop and replacing it with a high performance laptop. I was looking at laptops on ebay and quite a lot of them have foreign keyboards. I was wondering if it would be possible to convert the keyboard to qwerty but simp,y popping off the keys - putting them in the qwerty poisition, then tell windows that its a UK qwerty keyboard. Thanks for any help.
