SP 150mm SIGs and even towed division versions would still be highly useful. Without HESH rounds the 75mm IG is just not nearly as useful as the 120mm and should be replaced. At the regiment level four 120mm could do the same job as the entire IG company IMHO even without their direct fire capability. The PAW would have been an ideal IG/AT weapon replacement, but it was available far too late to matter. I'm partial to the tungsten ammo for the PAK38 (or a much better PAK38 Stielgranate 42 design...I mean why couldn't they develop a 75mm version that could shoot further and be more accurate?): https://upload.wikimedia.org/wikipedia/commons/thumb/e/ef/73_mm_PG-9.jpg/300px-73_mm_PG-9.jpgYou won´t get any objections from me that the German infantry guns were less than optimal. Personally I would replace both the 75mm and the sIG33 with 120mm mortars. The PAW came far too late, so either take the overly heavy PAK 40 or priotise Tungsten ammo for PAk38 on the regimental level until it is ready (with hand held weapons like the Panzerfaust and Panzerschreck widespread below that level) to have some long range AT ability. Less than perfect than what is available.
If they didn't make any of the squeeze bore weapons they should have had enough for the PAK38s:

The PAK40 should have been no less than a division level weapon IMHO, probably replaced by the 88mm field gun from 1943 on too.
I didn't suggest that the 88mm field gun be the main artillery weapon, the howitzers should be for that; an 88mm field gun would be a division level AT weapon and a CB/longer range harassment weapon that outranged the howitzers and other enemy division weapons they'd face. I'm not saying the PAK43, rather a "Kanon 36", a L56 (or maybe slightly less) 88mm field gun. Horse hauling is definitely doable with a weapon like that. A Opel Blitz could handle it too. IMHO the PAK43 shouldn't have been made for the reasons you describe and they should have made a field gun version of the L56 88mm.But I still keep to my opinion that an 88mm multi-purpose gun would be a disaster if it were the main light artillery of the German army, mainly from a mobility POV. Germany had in total less than 25000 vehicles which could move the Pak 43 reliably in anything but ideal conditions (not to mention the total mobility disaster the two-wheeled 43/41 was). And that are the vehicles which also move the German heavy AA and heavier artillery. OTOH pretty much any vehicle can move a weapon a third as heavy. And still the Wehrmacht had to give up PAk40s which could not be moved. The Pak 43 has obvious advantages in effectiveness over a 75mm divisional gun (which would have been far more effective than the pure AT Pak 40 of otl) both in AT and in artillery function, but strategically it can´t fill the same role. It would too often be impossible to get the guns to the position where they are useful. With the available resources it could only supplement it. The alternative would be to drastically shorten the barrel of the 88 to make it lighter, but that would sort of defeat the purpose to have a long range and high AT capablity.
