It sounds like you want a
Kirk Hammet guitar of some sort anyway. If I was you I would just go with a KH2. They are getting to be quite common on the second-hand market, and they usually only go for about £800. And for what you are getting, thats alot of guitar. The LTD models are good too, but they aint the real deal ESP. The quality of the real ESP would be far better.
Even though the Mummy graphic may be possible. You would have to somehow get in contact with ESP Japan, and their customshop, and get them to build you one. Not only would it cost you a fortune, but it would be hassle beyond belief. And unless you really want one, and you really have the cash spare, it just aint worth it.
A KH2 is the best way to get the Kirk vibe, feel, sound and look. And its the guitar that Kirk himself uses the most anyway. The only difference is the one he uses is heavily worn through heavy use and touring. And he has the "Caution Hot" and "Kirk's Guitar" stickers on it.
And you can buy those decals now anyway, so once you stick those on a KH2, you really do have the real deal. I dont see how ESP can charge an extra £1000+ for a relic finish and some stickers.
