My DP stays in place but is top heavy. I fastened it to a plywood base about an inch wider on each side. Made a significant difference.

Imagine the outriggers on mobile construction cranes. Something like that that is extended only when moving could work without becoming a tripping hazard when in use. Really only needed on one side of most machines depending on how you move it.

I really like Zachary's suggestion of putting 2 machines on one base. Gets the mind churning.
