hmm, well the key would be to get RBConstruction to work properly, and RBConstruction just uses the underlying mesh in order to pre-assemble the necessary (parameter independent) sparse matrices. Assembly for a given parameter then just involves taking a linear combination of the pre-assembled sparse matrices. If you can read the matrices in instead of assembling them, then I think things should work OK (though there may be some "gotchas" hidden in there somewhere...)
