No.

It's perfectly fine if the initial version of the td files are generated by a script, but td files in the LLVM tree need to be the primary source you work on going forward.

It think you would be better served by having a way of verifying the correctness of td files using your canonical architecture description. See for example Richard Barton's talk from the April developer meeting.
