Colour help, red to brown

I've a client with a 7/4 + 5/4 faded, looking to eliminate the red.
She's looking for 7 base with caramel and bright hi lites
I was thinking about blonder and 6%, 10/96 + pastel to tone, {not sure about the caramel yet} 7/0 (with 0/28 is this possible) during training we have never gone near 0/28 or any of the cool mix tones for that matter. sorry only pic i can find
