Oh, I'm so happy you're getting him a companion!

It shouldn't be a problem at all. Even in the wild, Konrad Lorenz often observed ganders forming pairs. They could still occasionally mate with non-paired females, but they preferred each other's company. Problems with ganders fighting generally only occur when a female is introduced.
Any specifics that I need to know about building the outdoor pen? They will be free ranging most of the time.
Adult geese don't need much weather protection. As long as they can seek shelter from heavy rains and storms - and seek shade, if it gets really hot - they'll be fine. Until they're fully feathered they should be kept warm and dry.
What they do need is to be protected from predators, probably much in the same way as your chickens.
Geese - and especially growing goslings - poop a lot, so keep in mind that they'll soon be huge birds and don't make the pen too small.
Geese love bathing. A plastic kiddie pool is perfect for two geese and easy to empty and refill every day. It also helps them keep their feathers neat and clean. Make sure to monitor their baths until they're big enough to get out of the pool by themselves.
