As I am wont to say, why Miqo'te? If the character is from Ishgard, why not play a race native to Ishgard? It would be like playing an African Knight in Scandinavia (considering Seekers in particular prefer the warmth versus the climate of Ishgard, not an amiss comparison in my biased opinion)
Of course, it's not impossible becaus it's not a law of physics. It would be considered strange in-universe, and this strangeness should be embraced into the backstory to make it more convincing.
