The DER can be reused, but someone has to go through every possible TPM structure that could be written to NV and define ASN.1 for it. Even more work is writing tests for all the corner cases. I wasn't suggesting inventing a random format, but rather using the native TPM binary formats that are part of its standard and for which implementation and test code will already exist.
