Wow! Congratulations!!! I actually have a dear friend with your last name, and I love the pronunciation.
[name]Kenzie[/name] isn’t my style (I’m a classic/vintage names person), but I can still appreciate names with a modern style. [name]Kenzie[/name] feels like a nickname for [name]Mackenzie[/name] to me, and like others, I personally can’t see it aging well. I can picture a perky little girl named [name]Kenzie[/name], for example, but not a doctor, CEO, or lawyer.
Also, because it’s going to be associated with [name]Mackenzie[/name] (and all of [name]Mackenzie[/name]'s yooneek spellings), I thought I’d mention that the [name]Mac[/name] names are very dated/trendy already, forever associated with the 1990s and first decade of the 2000’s. This may not bother you, but I thought I’d mention it just in case.
Have you thought about using [name]Kenzie[/name] as a nickname for [name]Kennedy[/name] or [name]Kendall[/name]? They’re not the best with Cote, but I think they will age much better.
I think that [name]Grace[/name] is a very pretty name, but it feels a bit like a filler because it’s used so often. (The same thing happened to [name]Rose[/name] in the middle.) I do love it, though.
I think that longer first names sound wonderful with your last name.
