Will this be possible if the US/AA mileage programs are unified before I can get the extra 20k miles?
Although that is possible with AA, it is not with US. There have been some reports that once US merges with AA then any changes will be handled the same where you can just apply extra miles to upgrade a flight with no fee, but i wouldn't count on it.
Can you sign up for US credit card or buy miles?
