Is it just the distance that is preventing you from asking any one in the family? If they are Catholic, and can travel for the baptism, I don’t think the distance would prevent them from being godparents.
The Godparents are not required to be at the Baptism. If you know someone who would make a good Godparent that is far away geographically, you can have someone else stand in as a proxy at the actual Baptism. I don’t think either of my own godparents were present at my Baptism and my youngest son had one “in person” and one proxy.
