Seems viable, but this set as of now is the standard, and for good reason. Experimenting is up to you, though. Personally, I'd test out the Pledge combo a couple of times, but ultimately return to the standard. Also, Pledge teams are now gaining popularity, and are somewhat predictable. I say, if you were to get predicted, you might as well go for power.
Anyway, it is my duty to say the added effects of the Pledges is actually quite a good thing, and may actually help you win, or (sometimes) catch your opponent off guard. But veteran battlers know that Pledge teams are fairly common, and will try and prevent you from setting it up.
tl;dr : I am of literally no use to this question, and I only exist to add more confusion.
