Can I translate Inoa to Majirel?

[Buttercup Honey]

Waiting on new Inoa to come in and my sis has been getting inoa 7.23 and its lovely. I'm not in salon anymore and she needs her colour, she has about 50% grey and base 6 natural. I was gonna use half 7.23 and half 7 majirel, would this be close enough until I can get Inoa.
Thanks x

U can use them separately but don't mix them together

Thanks:0) sorry for confusion, I wasn't mixing them together just trying to get a close colour match.
It was lovely x
