There was a guy yesterday at Just Dice promoting his new interesting project spacepirate.io and was mentioning at adding few coins in the future, and said he will look into GP. Maybe it would be good if you got in touch with him.
That sounds awesome. Is there a thread about it on bitcointalk? I would like to get both GP and HYPER added and will supply bounties and marketing.
EDIT: I think I have found the developer on bitcointalk and I have sent him a message.
