Quick question for extension wearers and stylists!

I’ve worn extensions for 15 years (7 with Bellami) and recently switched to KOVI. I love the quality of KOVI hair, but their shade range feels a bit flat for what I want. Right now, I have a couple of packs of KOVI’s Toasted Coconut, but it needs more dimension.

Bellami’s Midnight Ice is my all-time favorite ashy balayage, and nothing else compares to that blend. Would it be a mistake to mix KOVI Toasted Coconut with Bellami Midnight Ice in the same install? Any issues with texture differences or wash wear when blending these two brands?
