Help with a colour (pics attached)

Hi, I'm doing a client next week who previously has has alternate foils and 6/37 in colour touch.

Unfortunately she now needs a lot more of the colour touch, and I'm struggling to get enough foils in, I'm thinking of doing the blonde foils and then flooding with a colour but am unsure if what to use. I used the 6/37 I case I picked up and of the bleach and this worked well but I'm thinking it might be too coppery to flood with ?

I'd like to stick with the colour touch so she doesn't...
