existing spacecraft, what would be their “crush depths” in deep planetary atmospheres

(A)(1) what are “crush depths” for human crewed spacecraft repurposed as  unmanned planetary probes?We think spherical spacecraft might  work best due to equal atmospheric pressure on their hulls.at what point would they float do to bouyency? To pressurize or not?

(A)(2) Soyuz ,atmosphere probe

con ops,   Soyuz docked with another Soyuz with its service module with the leading Soyuz outfitted with a 23 Meter TEST deploy-able aerodynamic decelerator,into an elliptical   orbit with subsequent EDL days later with one or both Soyuz’s.Service module carries science and communication as an orbiter.

(A)(3) what is crush depth for a Soyuz at Venus or Uranus?

(A)(4) deployment mechanism for balloon probes? We suggest a rotary bomb dispenser for a fleet of balloon probes

(B)(1)Shenzhou atmosphere probe

con ops,   Shenzhou docked with another Shenzhou with its service module with the leading Shenzhou outfitted with a 23 Meter TEST deploy-able aerodynamic decelerator,into an elliptical   orbit with subsequent EDL days later with one or both Shenzhou’s.Service module carries science and communication as an orbiter.

(B)(3) what is crush depth for a Shenzhou at Venus , Uranus or Saturn? Titan should not present a problem for Shenzhou.

(B)(4) deployment mechanism for balloon probes? We suggest a rotary bomb dispenser for a fleet of balloon probes

Dragon/Dream Chaser,

Dragon with a 23 Meter “TEST” aerodynamic decelerator docked to the aft end of the Dream Chaser! what an odd flight stack.after achieving orbit Dream Chaser is the orbiter but at end of mission perhaps she could EDL? would she float?

con ops,   Dragon docked with Dream Chaser (aft end) with the leading Dragon outfitted with a 23 Meter TEST deploy-able aerodynamic decelerator,into an elliptical   orbit with subsequent EDL days later.Dream Chaser performs a second planetary interface to circularize her orbit, Dream Chaser  carries science and communication as an orbiter.
