Two things.
1. I think that just splitting a signal into two like that will do something weird to the impedance that the Factor wants to see? (could be wrong, but worth following this up).
2. What you are suggesting amounts to a parallel loop of course, which over the years has (too) slowly become to be seen as not a good idea; because even though preserving the analog path sounds good in theory, the phase cancellation you get with digital/analog in parallel yields an ugly unnatural sound, far worse than just analog or just digital. A series loop is the way to go.
