If two sets of identical twins married each other and had kids, would the cousins be genetically similar enough to be considered "siblings"?

Short answer: Yes.

Long answer: Since the Mothers and Fathers are genetically identical, then genetically, the children have the same parents. Of course, blood siblings can (theoretically) be as genetically distinct from each other as their parents are from each other, but that's *really* unlikely. (something like 2^-46 unlikely)
