Thanks.

Looking at some published specs, a 4.6is with an ESS supercharger will increase the stock hp and torque to 445hp/460tq... good for 5.2 seconds to 60mph... (almost identical 0-60 performance numbers produced by a stock 2003 E39 M5, which is very impressive for a 6000lb+ vehicle!)

On the other hand, the X5M produces 555hp and 501Nm torque... (good for a whopping 4.5 second leap to 60mph!)

Impressive specs, yes! ...but the short answer is still NO; you will get spanked by an X5M!
