A 22 & 6.5 Creed would be a nice pair. Just depends on if you want the second as a backup for elk. Then I would probably go short 30 something or even 338 RCM. The 308 is never a bad choice, it's at least 90% as versatile as the 30-06. Or just skip the 6.5 and do a 22 or 6mm Creed and a 30 something.
Also depends on how much overlap you want.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
