Escape velocity does scale with (square root of) radius so its not a dumb thought.

And I'm not a rocket surgeon but I could imagine earth rockets might be operating near some physical limits that make a 50% increase (or whatever) infeasible.

Wikipedia says energy = GMm/r.

if g=GM/r² then energy = mgr, proportional to r given g is constant.

apologiesMy previous comment was wrong, I derivated while integrating.
