this is quite hard cause 1. i haven't read this in 4 years. (but it was my favorite book i read in all of highschool so i remember it pretty well. 2. cause i wanna say one person is one thing but then i flip flop and say no this person would be better, but then it throws off the dynamic i'd set up.

anyway here's my 2 cents.

micheal-caesar (head of the office and whatnot... vain... etc.)
dwight-antony (i feel like he would be one of the conspirators to kill michael, but he's the only one who would defend michael should he be killed, make sense? also, he hates jim so turning the office against jim would make sense there too)
jim-brutus (i had a hard time with this one, cause he has a good heart, but is mislead with what he is told and kills caesar out of fear of what will happen to rome i can see jim being like this)
ryan- Cassius (cause he ran dundermiff for a while and had a bunch of ideas to make the company stronger but screwed them over wayy bigger in the end.)
Oscar/creed/andy- Casca (i feel like any of these people could get very carried away with this and go overboard and start the murder)
toby- Terminus cause i feel like even though him and michael don't get along he wouldn't have the heart to stab michael.

as for the others, i'm not sure and i'm too tired to think more. thanks for reminding me i need to reread julius caesar. also, good luck with your project. hoped this helped!!

dwight would be ceasar

if your class wanted a character for julius caesar it would be dwight because how hero like he is, and nothing gets in his way.julius was a brave hero and so is dwight
