He already served as Hand of the King. he is witty and clever; with a keen mind. He organized the defence of Kings Landing and held off Stannis Baratheon. He has much the same bleak cynical attitude and worldly advice as Jorah to offset Daenerys nieve chaotic goodness. He knows a bit about dragonlore. He is good with sellswords and Dany is going to have a lot of them. Tyrion is an organiser and a builder. Having him will be an excellent asset for Danys cause.
As long as he doesn't do anything stupid and get the hots for Daenerys. Then gets mad when she slaps him down. I can see them getting along and her not being quite as fussed about his appearence. Enough to befriend him.
