I think so. But really any old-school monster stats will work. I also think the monsters from Shadowdark would work nicely.
I think you're right. I've been comparing them to OSE and it's pretty similar.
I'd also pay good money for a full glaive monster manual
I have a very rough one for my personal use. But only add monsters that I use in my games 😂
A zine of tactically interesting monsters would be fun to do though.
