I'm not sure if they will work on the DFP wheel, but they do set inside the DFGT so maybe.
Flappy paddles for DFGT
There is now a place to find paddle shifters for your DFGT wheel. I loved my DFGT in all ways except the terribly small hard to reach buttons.

"All right, received these shifters today. Was a bit skeptic at first as I don't drive with manual shifting but decided to give them a go as with manual shifting you have even better control of the car you're driving (more accurate speed trough corners as you know which shift is optimal with precise timing).
Result? New personal record on Sakhir!!!! Simply love them"
