More aggressive rear diffuser. Will C7 one fit?

RS6 rear Bumper and Diffuser Conversion

I’m interested in refreshing my 2009 RS6 rear bumper to the later more aggressive style from a 2013 RS6. Can it be done? Has it been done before?

Would either the newer rear bumper and rear diffuser from a C7 RS6 (2013) fit the C6 RS6 (2009)? Or just the rear diffuser perhaps?

I know Maxton and iLR carbon do deeper ones but I really like that C7 look.

Look forward to hearing back from anyone with pointers or advice. Thanks.
