Yes...it is a nice modification to the 06-07 M's. I was able to swap front bumpers a few years ago and it really changed the look of my car. Of course, I went with the 'sport bumper' (2008) since it gave me the aggressive but classic look that I was going for
for both M35/M45 -- 06 to 07, the front bumper is interchangeable with the 08-10 models (sport/standard). You also would need to change the front grille. As far as the rear bumper, I don't believe they are interchangeable -- unless modifications are done for fitment as well as the rear taillights being replaced.
Just as an FYI, you can get the 08-10 front bumpers at InfinitiPartsUSA.com - the parts are OE and far less than getting them at the dealer.
I'm not sure if you searched my thread after doing the install, but here are some pix:
