Stationary support weapons are kinda underused. Not only are they easily countered by off-map strikes and - if that wasn't enough - pretty expensive in terms of MP, the commanders aren't that great either.
So, how could relic improve their viability without actually buffing them?
Here's my idea:
Once you reach the needed CPs, your Pios/Engineers can build them WITHOUT crew for the MP cost of only the actual gun. That would be 360MP for one LeFH, for example.
The crew needs to be built at the HQ FIRST for the rest of the MP cost - 240MP in case of the ML-20/leFH. You can only have as many PAK43s/LeFHs/ML-20s as you have crews.
The crew can then operate the gun OR abandon it whenever you want (in case of an arty strike for example). The mechanic already exists ( see USF). You can't just re-crew them with, for example, Grens to abandon them again to get a free Gren squad. Only the buildable crew can re-crew those guns.
Stationary weapons could still be destroyed by Stuka Dive Bombs or Il-2 bombing runs instantly BUT (in case you saved the crew) your next howitzer will cost way less than they do ATM. And you keep the veterancy.
Whatcha think?
Don't forget about railway artillery
