No, Joe, if you read my second sentence, I am agreeing with you, that you cannot change the mount on a particular back. My back swap was arranged with PhaseOne and was not a swap arranged within a dealer's stock. From memory, the back had been repossessed by a UK finance company and I don't recall a dealer being involved.
So, the OP should check with PhaseOne whether, if he buys a back with a mount he does not want, PhaseOne will swap the back for one with the mount he does want.

It is challenging to swap platforms with an investment into an older digital back. If there is availability, this can be ordered thorugh a Phase One dealer for $3,000 USD. But given the cost of older backs (like an IQ160, which may go for $6k - $7k - ish), a $3,000 mount swap doesn't make sense. Alternatively, you could swap with an end user or dealer, but still would be tough to do so affordably on an older back like that. And then you have the added cost of the camera.
You have not stated why you are pursuing a Hasselblad H_X Camera vs a Phase One XF Camera? Before the XF, we had many
hybrid users; those who would mix and match a Phase One digital back with a Hasselblad H camera. But with the launch of the Phase One XF, and with the newer Schneider lenses, the number of those who wanted an H camera with a Phase One back declined dramatically.
I still feel I may have an ergonomic preference for the H camera (the way it feels), but in most every other way, I prefer the XF. The fact that it has a substantial amount of technical integration with the Phase One backs is another important factor. Want to do something as simple as remotely control the settings of the camera? Don't put the Phase One back on an H camera then.
