Muting my Teal/Turquoise hair a bit with grey???

Hey!

So i recently relightened my hair/pulled up my ombre quite a bit and then re-dyed it all a turquoisey teal using a combo that was 90% turquoise and 10%blue of elumen. I had that done professionally, but I'm thinking of making adjustments with manic panic. It's slightly green at the mid range of my hair because it was the first time i'd bleached that part of my hair. the bottom few inches were previously bleached a bunch and dyed green to blue over time. so that part is very saturated turquoise. I know that if i just do a solid wash of manic panic voodoo blue it will sort of just fill in/smooth over that green bit for the most part. I did a sample swatch last night.

However.. I kind of want to try to get a more..  muted sort of colour, with greyish tones so that the colour isn't as vibrant. it's tough to explain so i'll attach a couple of examples of the tone that i mean, if not the actual colour.

My question is... would that be possible to do? like maybe if i got manic panic blue steel and washed it over it?  I know that the girls in the attached photos likely had white/way lighter hair than me. I attached a photo of how light mine is/was (that I took to laugh at how terrible it looked).

Let me know if you have any advice or experience with that sort of thing!
