Edgerunner's Inc had dozens of edgerunners who could either ally or oppose your crews (nothing personal if it's the last one, it's just a job). I don't know 2020 well enough but I assume all of the solos included are badass (they all have Combat Sense +6 or +7 which I assume is equal to a rank 6/7 RED solo) and these are my two favorite borg boys. The jobs are also good inspirations, but won't give you the beat by beat. All of the repositories should have it but I'll shill mine even though it's a bit outdated https://bit
There is Danger Gal Dossier but that's mostly gang enemies. It has an edgerunner chapter but none of them seem to fit your idea (Maelstrom might though).

I'm guessing Big Foot is a hardened mini-boss given the +16 combat statline? Custom martial arts is pretty nice. Also a big fan of 'Uh, yeah this tech-upgraded subdermal armor is +2 SP (SP 13 total) but it has a drawback! You need to have BOD 10 like every edgerunner and their retired 'runner granny doesn't have that'. Also an entire assault rifle tech-upgraded to be pop-up? I love the creativity but would like at least some fresh guidelines, considering Red Core is almost 5 years old now.
