Absolutely!!
First just to get out of the pension the company would owe a huge amount just to freeze and secure the amount that the current members have in there for retirement.
Also the company knows that no matter how good a 401k is, that a certain percentage of employees won’t participate in it.
Now, if we can get a automatic contribution from the company for everyone, and one that makes since, then except for the amount of monies it would take to get out of the pension, it would then be the same cost to the company.
