The far simpler thing to do would be to popularize both MCVE and MVCE as valid representations of the concept. There's notno reason why the C and the V have to be in that order anyway. Dealing with this common typo directly would be far easier than trying to popularize a new name and insisting everyone change a good name they've been using for years. If you can make help/mcve and help/min-reprex work at the same time, you can do this for help/mvce. Add a note to the page that it's also sometimes abbreviated "MVCE," and you're done with minimal disruption.
It is worrying to me that you did not come to the realization that each word bore particular significance yourselves. It shows me that you didn't examine why each term was included originally. You did not take the time to understand the intentions of the people who developed the original name and understand what it was trying to communicate. Instead, you railroaded it into what you thought was important. This is a common trend among modern SO employees, and it undermines my trust in the organization. Doing that goes against SO's core values, both in terms of how to treat other people and in terms of improving your own understanding of a problem.
If you had approached Meta about this change before implementing it, any number of users could have explained this. By implementing it before coming to this understanding, you have again demonstrated that you do not value your established community's thoughts on these matters.
