I could certainly use smallish hexes with larger hexes superimposed, the large hexes three small hexes across.
Done! Check out the Hex in Hex file.
Edit: Oops, I originally misread your request, but I fixed it and kept both versions. Hex in Hex (Three) has 3 hexes inside larger hexes. Hex in Hex (Seven) is what I think fits what you were asking for.
