I wish you all the best of luck with this. Having spent years tossing and turning over the very same conundrum, I've got a pretty good idea of what it's like. I had a good opportunity when leaving school & moving to university, but in the end elected not to due to all of the potential hassles from various places, but I certainly haven't ruled out changing it in a couple of years time. It's a really big decision though & not one to be taken hastily. I'm very glad for you though, because you've obviously taken the time to carefully consider the options & I'm sure it means just as much symbolically to you as it would to me. It's really not just a name after all - like you I wouldn't consider changing my name to some random one, but one with special meaning to me. All the very best :)
