I really like Blyton, but you're right, it's too narrow for loads of cars at the same time, I've done it in sprint format before, hence why I probably really liked it.
Blytons trackday/sprint format works well, morning open pit, afternoon sprint with 4 or so runs, I did it with approx. 50 others, space didn't seem an issue.
I'm always up for anything but have been let down by my car last couple of things so haven't been reliable
