I was thinking of the same. Incremental steps to expand LaValle. This is good for two reasons. Its more financially rewarding to expand it small increments and it will also keep the stadium atleast 50% filled so that the fans get a good perception and increased interest.
I think the first step should be completing the end zone seating at the scoreboard end. After that they can add a second tier to the "away side" just like the home side. That would make it 16k or so... Another expansion to "the Red Zone" endzone can be done to make the stadium reach a max capacity of 18-20k....
I'm assuming the largest capacity LaValle was designed for was 20k or so... So I don't expect it to pass that
