Multi-Contour / Comfort Seats Retrofit Possibility?

[DG3]

Hey guys, this forum has been amazing on my quest for the perfect 05-06 4.8. I thought I found the absolute perfect one for me but it only has the Sport seats. I have test driven X5's with the multi-contour seats...20 point articulation and mid-back pivoting (sometimes referred to as comfort seats). Being 6' 3" with some back issues they offered me a level of comfort and fit that I honestly never even imagined achievable by any vehicle. Really...and I do a fair amount of long drives for work.

So, is there any relatively clean or easy way to swap the sports seats for the multi-contour seats? My guess is probably not but I wanted to see what feedback is out there. I think half the trouble may be finding available mc seats. Then I'm not sure if it'd be very plug and play to swap them. Thanks for the feedback.
