I would assume the body and nose recover separately? If not, I would make it so. Would not want those two large pieces clanging together on the way down.

As to canopy area, do the two pieces way weigh about equal parts? Or, thereabouts? If they are roughly the same weight, then basically a pound under each 30” canopy (or even 36” canopy) is not a bad distribution. One wouldn’t be flying in a gale force wind, so those parts are not going to drift too very far under chute(s) that size.

The Centuri and Estes Saturn V lower segments both recovered under twin 24” chutes, and while twin chutes loose a bit of their overall drag potential when blossomed side by side, the lower portion of those Saturn Vs only weighed maybe half a pound, and they would tend to recover fairly rapidly under those two 24” chutes.
