I'm still not convinced your dub can't work Trooperman.
I don't like the voice in the rots clip to be honest, and I don't think yours is inferior.

But there are problems in the mix. The clip Ady posted is probably the best mixed of the clips i have seen of that scene. The voice is already more integrated than the early clips. I believe 100% that the 'sound' of the voice can be fixed with a bit more work. Of course I haven't seen the entire thing, so I don't know if there are places where the dub doesn't fit, 'acting wise'. For example I have an early clip of the garage conversation that doesn't quite work because you are talking somewhat quietly and Hayden looks like he's shouting. But I think you redid some lines right?
There also seem to be sync issues, but they're most likely fixable.

Then there's the club music, personally I don't really like it, but other than that it doesn't sit as well as it could in the mix if it's supposed to be ambient music, needs some aggressive eq'ing.

If you like, I wouldn't mind trying to do the audio mix for a scene. I do a lot of sound editing/mixing, usually with music though.
