By act of Congress, Iowa and Wisconsin are to be maintained so that they can be recommissioned if needed. However, no ones making the parts, so IF (pretty big damned IF) they were to be recommissioned, only one would go while the other became a parts bin.
More cost efficient is to convert a couple of container ships to carry 160 Tomahawks, a pair of rail guns and i'm sure you can find space to place a det of 2-4 AH-1Zs for recce, mid range defence and other odd jobs. Whats more is you change the profile of the ship minimally and max use of off platform sensors (most likely drones, satellite generated intel or EP-3) so electronically it looks like any other cintainer ship. But thats just my $0.02.
