Is there any good replacements for zombieman and wolfSS? (with dehacked)

[riderr3]

In my previous megawad I almost no used zombiemen, consider them useless. So for next map pack (limit-removing) I need change them to some useful mid-tier monster.

Also I changed wolfSS to plasmagun zombies. Probably the only issue - they faced to player when shooting to another side. May be I should change them to flying evil eye or something.

I can use some sprites from Realm667 website.

Actually you can add the rotation sprites and they will work as long as you name them correctly.

Maybe you could turn zombiemen into flying hitscanners (Strain has a nice flying robot, for example, you can use it).
