[Haskell-cafe] Haskell Jaskell Interface?

I was wondering if a good approach to java interoperability might be a Haskell Jaskell Interface. Jaskell allows some haskell programs to run on the java virtual machine and dealt with some of the issues with regards to interfacing haskell with java on the virtual machine side of things. Therefore if their was say a GHC bridge between haskell and jaskell their would be two similar languages talking to each other. Code ment to be more closely coupled with java could be coded in jaskell and code that requires say GHC extensions could be written in haskell and perhaps some io interface between the two languages.
