No, it wouldn't. Ostruppen are too poor in many different aspects. They are cheap and can't really hit anything plus they scale really badly. Give them stats and abilities of penals or cons. But, yes people choose them more often than not because the 6 models plus terrible stats still have enough advantages to be chosen.
Osttruppen actually have some of the highest accuracy in game - they just deal low damage, but they most certainly reliably deal damage. Their scaling is as any other mainline infantry.
They went through so many buffs and even got LMG upgrade for late game, that now they are very cost effective squad as long as you position yourself correctly.
