I am sorry, but this doesn't make sense. You just can't have multiple defines of the same thing.

I think you need to start over by taking a close look at how inputs and outputs to INLINEASM nodes work in the DAG. It's a lot like function calls. Then figure out what the DAG should look like with GPRPair inputs and outputs. It shouldn't be very different.
