This is a long shot but if anyone has a X5 4.4 with no engine in the bay and access to an LS block I will mail you my engine mounts off the E39 4.4 to see if they work and clear everything on the X5 chassis. And you can keep the mounts as a gift if it works or I will atleast supply return shipping if it doesn't.
