One of the things I mentioned in another backstory revamp thread is that an interesting and productive backstory is a backstory that can be engaged with on some level. The reason why I ask the question "what story do you want to tell" is because that question will ultimately influence what portions of the backstory are made available.
Assuming that you want something transformative for your character, the first thing you'll want is some sort of conflict, not just on a "we're going to war with Garlemald" level, but on a personal level as well. Without this, my fear is that the character's plot will boil down to her running around and going "wow, Ala Mhigan culture is so cool!" This isn't necessarily a bad thing, but if it's not what you're looking for, there generally needs to be an extra spark of conflict or hook of investment that ties your character to this portion of their backstory. Otherwise, there's not much connection; even a non-Mhigan can experience an "I really like this culture and want to aid it" moment; it's nothing unique to your proposed changes, and would likely be doable already with your character's current backstory, whatever that may be.
An easy connection is familial, but without any idea as to what that family did, or what their opinions or wishes for their country were, it's hard for me to give you options in that regard.
I think a good starting point is brainstorming exactly what you want this cultural connection to mean for your character, and what this tie actually pulls them into that isn't benign or easily escapable.
