Can three #8 and one #10 wires be in ½†metal conduit?

It's usually easier to just oversize things and skip the calculations. I have some interest in shoehorning (within the confines of the rules) conductors and grounds into 1/2 and even 3/8 steel flex, in order to make some new wiring look like older wiring that's been there for awhile. That has me running the fill calculator, with both solid and stranded THHN, and scratching my head over what is or isn't considered a full-load conductor.
