Toner question

I have a toner I always use after I box bleach my hair (both are boxes) and it usually turns my hair purple very fast and then washes out to my desired shade in a few washes. I have to be somewhere tomorrow so I was wondering if I could add some conditioner to dilute it a bit? I have super thick hair too so I was thinking it would go alot further too in covering my hair. Any help is appreciated!
