home hair dyeing - help!!

About a month ago I went into a hair school for my hair to be dyed ombré from my natural brown to blonde; I walked out with a weave... my plan was to dye my hair ombré blonde so that one day I could dye the blonde part pink... well, that day has come but the ombré is still not in the picture. While doing some research I decided that ideally I’d like to bleach my hair from the roots to the end then dye it all various colors of pink, is it risky to do so because of my weave? I have many different levels of bleached hair within my hair and don’t want to damage anything while trying to get it all the same-ish color... advice??
