According to the lore book in my lap:
Racial Distrubution: Highlander Hyur: 60 %, Hellsguard Roegadyn: 10%, Midlander Hyur: 10%, Seeker of the Sun Miqote: 10%, Other: 10%
So yes, there was definitely a presence of the other races in Ala Mhigo. There's also several people here on the RPC that roleplays Miqo'te's with such a background, and it's certainly an interesting starting point I think. Go for it
