What viable alternative design would not have this constraint?

A smaller purpose build lander that doesn't need the fuel capacity for the entire journey would be significantly shorter and could be wider too. That would get it significantly closer. Enough that a simple ladder would be viable so they aren't reliant on a winch/elevator.

So you're suggesting something similar to the Apollo LEM that will land, and carry enough fuel to return to orbit to dock with something that will contain enough fuel that will return to Earth?

Wouldn't that make the mission unfeasible because it requires ISRU of return fuel?

The Starship version of the Mars mission also requires ISRU. At least that's what was presented.
