Same Day FP at different Park

[NYHeel]

I'm going to be heading to Disney for only one day (old unexpired day on tickets from summer 2001) in late October. I'm mostly planning on going to the Magic Kingdom but since it's only my wife and and I, it's possible we may have time to head to a different park in the late afternoon. Could I get a same day fast pass for Epcot, HS or AK from the kiosks in MK once I use my 3 MK fast passes?

I'm thinking we could probably get out of MK around 3-4 in the afternoon and try to catch some of the good rides at a different park afterwards if FP was still a possibility.

No.
A real drawback of FP+.

This kind of information is explained in the FP+ thread found HERE. Read post #1 and #2.
