I think it has been made plain on this and other LCS threads that the module-swapping idea as implemented on the LCS has failed miserably, and these ships will in fact effectively become single-purpose dedicated vessels. That blows your whole 'modular' argument out of the water. So for those set up as minesweepers, we now have minesweepers that cost ~700 million each. That strikes me as one of the most obscene program failures in U.S. naval history. Well, I guess we can take pride in having the highest-speed minesweepers in the world. We will win the minesweeper drag races for sure!
As for 'sympathy for my suggestions', a debate is not a popularity contest for ideas.
