Here are Dimitry's calculation for the Vulcan.

BE-3U version of VULCAN

Rocket Vulcan II

Total Gross Mass 430 Mt

Payload to GTO 8.85 mt

Payload to LEO 20.2 mt (all figures below are for GTO launch)

SI Gross Mass 362.36 mt

SI Propellant Mass 340.30

SI Separation Mass 22.06 mt

SI Diameter 5.1 meters

SI Engine(s) 2xBE-4 LNG/oxygen engines

SI SL Thrust 500 tf

SI Vac Thrust 557 tf

SI Isp SL/Vac 307/342 seconds

SII Gross Mass 56.30 mt

SII Propellant Mass 49.87 mt

SII Separation Mass 6.43 mt

SII Engine 1xBE-3U hydrogen/oxygen engine

SII Thrust (Vacuum) 50 tf

SII Engine Isp 450 Seconds

PLF Mass 2.478 mt

PLF Diameter 5.1 meters

Separation time 220 seconds

A Blue Origin 4xBE4 SI + 2xBE3 SII LV should be capable of 40t (approx 10t per BE4). Partially reusable approx 28t (30% penalty) and fully reusable 20t (50% penalty). For LEO HSF these payloads would be overkill for 7x crew 10t capsule but would allow for a larger capsule (15-20 crew) in future. A 40t LV maybe a bit light for doing BLEO missions in one launch without in orbit refueling (eg ULA distributed launch), but as RLV it should be able to deliver fuel to LEO for <$2K/kg.
