With that being said, I ordered CF/cleared sheet that has adhesive backing already on it from Dragon Plate:
I made cardboard patterns of the end slot stickers and center slot insert, traced onto CF sheet, and cut out (you can cut the stuff with a good pair of scissors easily). I then attached to my iS/Sport diffuser & voila! had matching CF to rest of exterior parts.
I was in same boat as you - OEM M3 CF Mirror Covers, CF Grilles, CF Eyelids, rear spoiler with exposed CF edge - wanted CF on diffuser, but didn't want to wrap as it would not match rest of stuff.
For now I have the finned section in matte black, but I might break down at some point and buy the aftermarket molded overlay...
