Litreocola

I have an S5 bumper on my S4. I've always liked the look of the black trim and I'm intending on having the trim painted black when I have the car painted. The car is already a mix of S4 and S5 on the inside, so a bit of that on the outside makes sense I suppose. The molding looks really out of place to me though (especially since it's line-to-line with the S4 molding).

Will I have any major issues fitting S4 moldings into the S5 bumper? I've been looking around for this, but all I can find is people adding S5 moldings to S4's.
