Looks to be a nice way to start an engine. However, from looking at Comet's own photo of the result in the magazines, it seems they've used their standard crosshead. This to me is too small, making the slidebars too close together. I first noticed this in Tim Shackleton's book when he built a 'County' using Comet bits for the valve gear. Maybe you could investigate whether the crossheads and cylinders can be re - used from the Bachmann chassis, with slidebars replaced and beefed up. I have one of these to go into shops one fine day - I find myself unable to resist just a few GW engines for the new layout.
So I've looked at this, Roche says 5.2mm, Bachmann says 5.1mm, Malcolm Mitchell (as Churchward) says 4.5mm and Comet says 3.7mm.

I think that I first suggested this source on June 20th but Mr. Venton was committed to using the items supplied with the kit- good luck to him.Also there's some very nice machined nickel silver ones from Markits. But I don't have dimensions for these two, so no idea if they're any better than the Comet ones.
