Personally I feel the main value of going to Mars is figuring out if it has or ever had life. That kind of search will benefit from scale. More tools to do more experiments, range farther from home base, maybe multiple landing teams. We could find ways to use an arbitrarily large payload. I guess that's not exactly what GP had in mind, though.
