Shoot, I woke up last night about midnight and thought to myself- 'self, the V11 already HAS a hydraulic clutch'. I was projecting my old Tonti and Loopframes.
Man, I miss my bikes.
So, what you might be able to look into is a radial master cylinder. Some of those have adjustable piston sizes, so as to make for an easier pull.
Also, you could change out the clutch. Not sure that's much more expensive than a new hoopty brembo master cylinder.
I don't know that this has been done on a Guzzi, but I've read about it elsewhere. So- just to be clear, I am NOT suggesting this. You could put in a standard clutch and leave out two springs. I kind of doubt that's a very good idea though.
