Fred noted that the Vostok used the 20mm tube. I was wondering if a larger size could be made to fit.

I had one of the originals...IIRC the stuffer tube was pretty tight...you might have pushed it with careful work to ST-8 ..which does not seem to be worth the work involved

Well...(since he confirmed that a bigger tube won't fit), maybe vented rear-ejection would work? The ejection could be vented into one of the four boosters, with a stuffer tube installed inside it which would hold the parachute. A balsa nose block (which would fit into the stuffer tube) could be epoxied to the booster's rear wall that carries the scale engine nozzles.
