PS3/4 stick to XBox 360 converter?

[PowerOfLegend]

Does anyone know if a decent converter for this exists? I just got a RAP4 for PS3/PS4, and I'm trying to make the switch from pad to stick. I was thinking that I'd like to run through the MK9 challenge tower to help acclimate to playing with a stick, but I don't have a PS3. I own MK9 on the 360, though, so I'm looking for a good converter.

What does everyone think of this converter? I thought I heard Pig of the Hut mention it during his commentary for MKx at CEO.. I wouldn't mind using my DS3 wired at least than using the PS4 pad.
