The only "risk" I see to that build is if he threw in a raven for PDD, cloaked his banshees and used the vikings to snipe the obs.

You want HT's for the Banshees, while having a way to kill the Thors (Immortal/Carrier), with the obvious inclusion of Zealot, Stalker, etc to support. You also need to have a few obs placed around near your army, to call them over as he snipes them.
