Changing the Enigma machine is simple.
So why didn’t they do it more often?
Changing user behavior is hard.
No it’s not. In the military we have these things called “orders” - if you want people to do a certain thing (or stop doing a certain thing) you put out a set of “orders” and generally speaking the vast majority of your military personnel do (or stop doing) that certain thing. Those that don’t can be reprimanded or even jailed if they fail to change their behaviour.
You're going to need to convince every mid-grade Heer, Luftwaffe and Kriegsmarine officer to put one of his better officers onto cipher duty, and rotate them out once they start getting too cocky.
Exactly, you’re going to have to be professional about it.
You'll need to make sure said officer doesn't train his replacement by sending a bunch of dummy messages.
Yes, you’ll need procedures that don’t help the enemy to break your cypher.
You'll need to deal with the blowback of said mid-grade officer's bosses saying 'This crap is only happening because B-dienst don't believe in their own equipment.'
Then the Admiral running your intelligence service will have to clamp down on that sort of behaviour.
And if you're really unlucky, seeing as how you just admitted Enigma was worthless, Hitler will get the idea in his head that poem codes should be used.
You haven’t admitted it was worthless, you’ve admitted there are procedures to follow to keep its efficiency. That there are ‘offensive’ and ‘defensive’ actions to be taken in this sphere of military activity just as there are in all other spheres.
What I actually meant is things more like use it less, don’t use it to transmit a weather report prefaced with a word-for-word identical opening praising der fuhrer every day (IIRC), accept it might get compromised and plan accordingly.
Just because OTL the Germans were terrible at it, doesn’t mean it’s impossible to be better.
