Landing an Apollo like capsule on rockets is -- of course -- an idiot idea, unless it's a final impact softening like Soyuz does. But for a VTVL vehicle, it's a different story. The vehicle has a much lower mass-per-square-meter of surface (lot of empty tankage), so atmosphere drag will be more effective in slowing it down. It's already got tanks, and rocket engines and vehicle structural support strength enough to be able to sit fuelly fueled for launch. All you need is landing legs, radar, throttleable engines, and fuel. Certainly, a parachute brake system could help. That boils down to design tradeoffs.
