The 2-1 system will be interesting. Looks like you're planning a system like the one I was planning for my 750 (until I happened across some ridiculously cheap hi-level ti Termis).
Its always seemed to me that there's little point in carrying around two cans when one will do the job.
I like the look of the single can system too.
One thing that concerned me slightly was the fact that, in the std system, each cylinder exhausts through both silencers simultaneously, hence the pressure pulses will be much higher in the single can and I was concerned that this might tend to blow the can apart.
I guess there may also be a problem of getting enough silencing out of just the one can, though many would not see that as too much of a problem.
Stuart runs a 2-1 on his 750 though, and I don't think he has any problems with it.
There's something pure, natural and clean about a single can system.
Personally, I would say that, in your mock-up, the can looks a little long and might look better with a longer collector section and correspondingly shorter can.....just to mess up your calculations.
It might be easier to get maximum ground clearance that way too.
Looking forward to seeing the finished result.
