I'm not stating that you wouldn't see Panzerstellung in the Twilight War, but one reason that they featured in the waning days of WW2 is that German manufacturing in the last months of the war* was so disrupted by allied bombing that they were having a hard time producing entire tanks, and fuel was in very short supply for the same reason. Chassis/engines were harder to manufacture that turrets, and there wasn't enough gas for new tanks anyways, so homeless turrets were used in fixed fortifications instead. In the Twilight War, manufacturing would be disrupted much more abruptly, so you probably wouldn't end up with as many "surplus" turrets as the Germans did during the last six months or so WW2. I reckon Panzerstellung would be a lot less common in WWIII than in its predecessor.

*Panzerstellung featuring obsolete tank turrets armed with MGs and light canon (Tobruks, I think they were called) were constructed and employed earlier in the war (like in some of the Atlantic Wall defenses). I know that in some parts of the Soviet Union and Switzerland, of all places, obsolescent tank turrets were emplaced in fixed fortifications defending strategic passes and such.
