I thought I could lower the rear but am curious to your thoughts

Hey... and if I recall you used to be m32 there as well!
Frankly I do not know for sure if it CAN be done, but I know that unless you re-engineer the suspension geometry you will have issues. The electrodynamically controlled struts come in one flavor- so to replace the struts with coilovers (required to lower the body and maintain suspension travel) you need to replace the adaptive drive units with plain units.
Look at what we go through on the 996TTs.... to drop the body you go to coil overs. Those that buy the "H&R sport lowering springs" have less suspension travel and have a shock damping rate that is now 'not matched' to the springs.... You need to lower the upper perch, retain the same travel and match the damping rate to the springs.
Once you lower the body, then you deal with suspension geometry- usually when the body drops the camber increases- you can dial some of this out, but only so much. You'll need adjustable links (ie dogbones, etc) to set the wheel alignment to the new lower position.
Perhaps there are people making such suspension parts for the E70. Frankly I cannot see much of a market for a $4000 coilover kit for an X5...surely for the 996TT, but most X5 drivers will just slam it down (if they like the look) and grit their teeth.
back to your car- if it is a 2009 or earlier and HAS the "Sport Package" it has adaptive drive. Sport button is (I think) an indicator. In 2010 the adaptive drive was a separate option.
