Nope. Until there is a set qualifier system instead of a popularity contest, Iowa isn't getting in the CFP unless we win the B1G. Small market teams ain't getting in when there's advertising and viewership money in play.
I don't even thing the B1G champ is guaranteed. Like the year NW won the west. Let's say there was a fluke game and they beat OSU in Indy. There's a negative 50 chance they let the Fighting Titzgeralds in the CFP because they have about 12,000 fans in the stands by the 4th quarter even when they're winning, and probably about just as many TV viewers. A team like NW could go undefeated 13-0 And they'd never get in.
Iowa isn't at that level obviously and with a B1G championship we'd get in, but that's the one and only way.
