An average Danish adult is 1.80 m, so I would be off by 0.05 m. That gives me an additional 9,000 litres of volume in the main stage, which can hold 3,240 kg of extra fuel. It also gives each SRB an extra 1.47 cubic meter of volume, or an extra 2,980 kg of fuel. This gives me an extra delta-v of 144.8 m/s, which is still a far cry from the 11,186 m/s you need for escape velocity.
