Yes, it can be done and they fit great. I got the seats from a junkyard for $200 each (I found the seats using
http://car-part.com, see page 2 for details) and it took me about 2 hrs each to do the install. I ended up using the bottom part of the seat frame from the base fiesta seats and putting the ST3 Recaro seat bottom and bolstering on that. Then I bolted the Recaro seat backs to the retrofitted bottom seat frames. I took very detailed pictures of the whole process and then dropped my phone in water the next day, Doh!
Notes about electrical connections:
Nothing from the ST3 seats plugged right in to the
Fiesta Harness. The airbags use different connector types and the seat heater connections dont exist on my car. The passenger seat pressure sensor was not swapped because I used the bottom half of the Fiesta seat frames anyway.
Here is a picture of the completed install:

Edit: I was able to recover most of the pictures from my phone!
Here is the drivers side Recaro vs. Non-Recaro. This Recaro is full leather and full electric and with
electric heater from a 2014 FoST.

Here are the seat bottoms, the attachment points to the car are different, so the FoST Recaro will not bolt right into the FiST

The mounting rails are riveted to the bottom seat frames and will not be easy to swap between the two seats, this can be seen pretty well in the next 7 pictures.
Because of this, the strategy is to use the FiST bottom seat frame with the FoST upper seat frame bolted to it (the tops and bottoms are easy to separate with a few bolts). The FiST bottom seat frame will then get wrapped with the FoST Recaro leather and bolstering (the
heated seat wiring is inside the bolstering and will come over with it.)

Here you can get a good look at the difference between the FoST Recaro seat wiring and the FiST non-Recaro wiring. On the Recaro all of the wiring goes to the one large block connector at the bottom left of the picture.

Here are the two bottom seat frames (passenger side) with the covers and bolstering removed (FoST Recaro on left, FiST non-Recaro on right). The
black plastic piece on the Recaro frame supports the thigh bolsters and can be moved to the non-Recaro frame by drilling out the aluminum rivets (I think there are 3) and then riveting or bolting it to the FiST seat frame.
The seat belt switch and the pressure switch (passenger side only) remain on the seat and will plug into their original connectors. The airbag on the FoST Recaro top seat frame could be plugged into the FiST airbag connector but will need an adaptor. Disclaimer: I haven?t actually tested that this works because I don?t want to crash my car to check it, but I am hoping that the side airbag in the Recaro seat is triggered the same way as the side airbag in the non-Recaro seat.

Here is the FoST Recaro seat with the side plastic trim removed and the seat bottom leather and bolstering removed. The side plastic trim was almost identical on the Recaro and non-Recaro seats and I ended up using a combination of the trim pieces on the final install.

I don?t know what this is a picture of ?
