It feels silly that red eyes would make them so invulnerable, would make much more sense if they were former soldiers with helmets or had biker helmets or something.
#Red eyed zombies should not be tanks - let them be soldiers with armor or something else instead

Yeah military or police zombies with riot gear would make sense or maybe even big body builder zombies or country lumberjack types

I think the red eyes should stick around. My reasoning is the following:
Bloody: Tougher, do more damage
Red Eyes: Tougher, higher infection chance
Bloody red eyes: Tougher, more damage, higher infection chance
Runners: Fast, loud, deadly
Banshees: Supposedly similar to screamers, but currently inconsequential since they don't work properly
(Moving on to your idea)
Armored Zombies: Super tanky, chance to drop ammo
Bloody Armored: Ultra Tanky, higher damage (small ammo drop)
Red Eyes Armored: Ultra Tanky, higher infection chance (small ammo drop)
Bloody Red Eyes Armored: Ultra Tanky, higher damage, higher infection chance (can drop ammo, or even a grenade)
While I get your point, the red eyes could be explained as an evolved form of the virus. By using the currently existing variants, and converting red eyes to correlate with the new infection system coming this month, the following variants can be made to completely change your approach to areas or the dynamic of the round.
