I'm not seeing it. Tyrion's first loyalty is to himself. Cersei still wants his head, and he knows it. (He probably doesn't know that Jamie wants to kill him for Tywin's murder.)  For Tyrion to betray Daenerys in favor of the remaining Lannisters would be suicidal.

Look where he is, now: Hand of the Queen, and trusted advisor to the leader of the most powerful military coalition that world has ever seen. He's never had so much power and influence, and can't expect to rise any higher. He's good at this game, and enjoys it. (Tyrion & Varys, late in Season 2, I think.)

If he wants to save Jamie's life, he can do that from where he is. "Capture alive, do not kill." Tyrion will persuade Jamie to bend the knee to Daenerys. Not Cersei, of course, but that's her stubborness.

If Tyrion is half-Targaryen, he'll never find out. How could he? He's not fireproof (Season 1, hot wax game with Shae.)  Jon may learn his lineage from Bran, or from Howland Reed. There's no such revelation for Tyrion.
