Better yet: present it to UK concert/festival arrangers or the like, or better yet, make the arrangements yourself (perhaps in collaboration with some club/venue)! No matter how many people over there want to see the band, it's just not possible to simply fly over and do a gig.
There has to be a pull from the other side, stronger than just people wanting to see them. There has to be someone willing to do the practical things, manage the huge logistics involved in bringing a whole band overseas.
That said, it won't hurt to show it to the band (posting it here is pretty much equivalent to that), maybe it can be used as an incentive for Spinefarm helping with arranging something, even if I think that's a bit far off yet.
