adaptations for land-based octopuses

This is a follow up question to: How realistic is the Swampus?

What adaptations would current octopus have to evolve, to become land based, meaning that they spend at least 1/3 of their time on land?

How long would the development of such features take, and can you come up with a scenario, that makes land based cephalopods plausible?

Helpful traits I came up with:

1. leathery skin, so they don't dry out in the sun
2. ability to breath air, similar to lung fish?
3. the redevelopment of their internal shell to support land based movement
4. development of a joint based internal shell in their arms, to support movement
5. improved camouflage abilities to avoid faster predators
