I'll definitely use steel tube for the last bit but have located a damaged log/ALR dd and will at least try that first.
I'm conscious with all this that crank will be my limiting factor in all of this - i.e. I'm using an old, and standard, one.
The other reason I'd thought 1" was precisely because of the piston travel. I'd read the ?Hazzard SU book (you'd recommended some years ago, I think) and thought I'd got my head round the issue of piston travel. This engine will again be crank-limited, standard cam, ported a bit and radiused tappets - and just rely on being as light bodily as possible. It worked well with the Woodie with a standard ruby manifold... and 26VE which is only about 17mm choke? (So this should fly with a bathtub on top of the chassis and retaining the lighter uncoupled system).
