Wally has to face the twelve original Gold Saints in their respective Houses, except for the Gemini Saint. In the Gemini House, he'll fight against the Gold Cloth manipulated by Saga as it was against Shun and Hyoga, and face the actual Gold Saint in the Pope's house, assuming he makes it. Speed is equalized with the Golds (wouldn't be much of a fight otherwise, duh! Still puts him at lightspeed, so it could be worse), but Wally has access to the full SpeedForce Bag O'Tricks (IMP, Speed Steal, D-Dump into the SpeedForce, whatever), so it will essentially be a battle of esoterics.

Bonus Round: Same as before, except that this time, Wally has to fight in each house (Gemini House included) against a composite of its sign's Gold Saints, if a Gold appears in several media, each incarnation is thrown in the composite. For example, in the Cancer House, he'll fight against a composite of DeathMask (Original+Anime+Episode G), Manigoldo, Deathtoll, Schiller and Sage. God Cloth feats from Soul of Gold don't count.
