6922 preamp idea

I would like to build a line stage preamp using a pair of 6922's and as few parts as possible. This is my second attempt at creating a circuit like this. I think I've got it, but of course it would be wise to get some more knowledgeable people to view it before I build it and subject it to high voltage.

So does this make sense, what I've done? I've attached the schematic and the load lines for both stages.
