[Haskell-cafe] package code duplication

There was a question recently about being allowed to get into package internals, and I had a question. I want to use uvector's stream internals in ways that the exposed methods don't permit, but I don't especially want to use another package (e.g. vector, which does expose its internals) or reimplement my own stream fusion. Would it make sense to duplicate uvector's internals, copying licensing information and other stuff of course, inside my package? It's a suboptimal solution, but it seems better than the alternative...
