Anyone here know how to change a unit's third tier promotion animation?

Like the titles says I would like to ask a favor for anyone who knows how to this.
Basically the favor is that I want you to change a certain unit’s third tier promotion animation in a certain hack. Although this is a favor I can’t really give you money, a life, my life, etc. Please be reasonable on what you want in return.

Obvious questions I’ll get from this:
Why won’t you do it yourself?
Well the thing is my laptop is busted and I don’t have the money to repair it.

Why do you want this to happen?
It’s because I’m tired of seeing the same thing over and over again.

For the one willing enough to do it please comment your answer and I will send you the ROM and animation and I’ll tell you who will you change.

There’s a lot wrong with this.

Don’t word your request as a question.
Be specific with your request.
Don’t have such an attitude when making such a request.
And don’t share ROMs (why do I even need to say this in 2022).
I’m going to close this now.
