Grille as a cheaper reward for the Brummbär?

From the historical point of view, Grille was a self propelled artillery gun so it would fire its shells like Hummel, not like Brummbär. Ostheer features a lot of indirect fire weapons already, such as the lIG18, Panzerwerfer and Wespe. We'll see, but first wait for Ostheer. It's not the time to discuss reward units for a faction which is not even released yet ;)

Would be alright, but the current Opel Blitz entities are too tough IMHO. I've spawned them using CheatMod and afaik they're based on halftracks--the only issue being i've had them bounce zook, shreck, RR, and even tank shots on a regular basis.

Keep in mind that that game mode could turn into the Operation: Assault range of mental retardation with players camping the opposing convoy's spawn.

i don´t want to be a bore - but can i pick up the idea in this tread of an infantry only mod again?

just like you have taken out the population limit - wouldn´t it be possible to have a parameter (on skirmish) that will limit the amount of tanks to 1 (one)? per side.
and 2 AT Guns on each side.

this will offer a totally different strategic experience i suppose.

the russian heavy artillery is limited to one also. so i guess it must be possible somehow.

Sure, that would be possible. But keep in mind that balance is an important, if not THE most important factor in PvP games. Some factions can't live without their tanks and would therefore have a penalty when it comes to infantry only battles. To have an example - Panzer Elite offers few, small infantry units which are useless without mechanized support units - in contrast to this, US Rifles can almost to every job once they're equipped with Stickies and BARs.
To get rid of those unbalanced aspects, we'd have to change the faction design which would harm our codex - not to change vanilla gameplay.

Also mention the fact that not all AT Guns deal the same damage same goes for tanks. Would be hell to balance and not worth the work.

I played an infantry only game and the PE is at a huge disadvantage. Against MGs and Snipers, they suck. Wehr is okay against US. Brits........ughhhh :P

soviets would own though. once they got guards of course.

Yes I would imagine SU would own. Snipers, spotters, Guards, CS + vet, endless Conscripts. Oh gosh O_O
