Mark will be blown away by this!!!
Perhaps you could bring someone to film the event when you present your lightsaber to him for signing so we can all share the moment. He's a really nice bloke to approach. As a volunteer I got to meet him backstage at Celebration Europe in London. Take your time, there is probably going to be a long line and bring some extra cash too since his signature along with Anthony Daniels (C-3PO) were amongst the most expensive ... albeit that was back in 2007 before the credit crunch.

Mark LOVED it!
Going in, it was all morning in line to get it signed. I debated the whole way leading up to it whether to get the battery can or the plaque signed, and finally just decided to get the can signed.
The people at the door to the booth really liked the saber, and all convention it turned heads.. But the real joy was when Mark saw it.
He did a double take when my wife said I built it myself. He said it was so much better than what he had on the set, and told me about how the original one had metal tracks that cut his hands, and how uncomfortable it was to handle. He said mine was much more comfy, and really liked the inside, and how it lit up. He sat and talked to me for a few minutes about it and thanked me for bringing it.
I had paid for one signature, and when he was done talking to me about it he said, "Yeah, I tried getting it all on that round part" and I said, well, I had this plaque here if you couldn't, but that looks fine... and he said, "Here, I'll sign that too" and snatched it out of my hand and signed it and handed it back to me grinning, like he knew his handlers hated when he gives out free signatures.
He really was so gracious and nice, and a funny fellow. Unfortunately, they did not allow photography at the table, but I will never forget him shaking my hand and thanking me for bringing it for him to sign.
Now I have the battery can AND the plaque signed. He solved the debate on how to get it signed!
