Can Sky Stretches to Shore let you, during the Slow Phase, Repeat an already-used Fast Power? (Assuming you have a Repeat from somewhere, like Powerstorm or Gift of Strength.)

Yes. Even after a Power is used, it stays in play, and can be modified - there's just usually little point in doing so. So the Fast Power can be made Slow1 with Sky Stretches to Shore, then used via the Repeat.
1 Effects reading "Use a Power as if it were (Fast/Slow)" should be interpreted as "Make a Power (Fast/Slow)", and would have been better phrased that way.
