I think you can operate the iFocus motor without a gimbal by using the Wireless Follow Focus Hand Unit. I tried putting a link but the comment didn't post when I put the link with it. Just search for it on store.gudsen.com
If the other gimbal has the correct threading and weighs the correct amount then I imagine you could mount it to the Slypod Pro but you would have to control the Slypod and the other gimbal independently.

I believe you need one of these to operate the iFocus without a gimbal since most of the gimbals have the wheel built-in to the handle. I imagine anyone would need the hand unit though when operating the iFocus on the Slypod even with a gimbal because the Slypod would be moving at the same time you're trying to use the focus wheel on the gimbal handle.

I just bought the slypod and ifocus, does it work without the gimbal?
when I power up the slypod and ifocus, then do the network pairing, it would pair just fine - but then what?
how do I tell the ifocus to start scanning the lens ?
when I try to manually rotate my lens with the ifocus attached, it is impossible as the ifocus refuse to sense the lens rotation
