This is extremely unlikely, I'm afraid, Oa has several different visual representations but more importantly, is a planet. It's unlikely to ever be needed for the comics, so I don't really have any reason to make it. I'm also low on Marvel maps, here are the more likely ones:

Yes there are a lot of DC ones on there as well as Marvel, but it was for variety.
Also, it's not necessary but I do reccomend you make a Wikia account. :P
