No, Trin is important (and if you wanna swap a Sakrohm, take out Uranus since He is weaker in T2S). Getting the Sakrohm bonus every now and then in combination with Morphun is really important in later stages.
Imho the only card that could be replaced by Stanly is Wee Lee. Has to be tested if the missing DR hurts the deck. Stanlys ability should be good enough to keep his lower power in comparison to Wee Lee.
