If I was an agent, I'd just make the match begin with Brock bum rushing Goldberg and have him take a few suplexes, nothing crazy like Brock did to Reigns but enough to have Goldberg look like he's legit concussed like Taker was(here's hoping Goldberg can sell that good) have his hope spot, exchange some holds to give him time to rest up and then Goldberg does his spear/Jackhammer combo, Brock kicks out. Then he sets up for another spear and this time Brock counters with the kimura and he either taps out or takes an F5 for the win.
Could have Brock do the big bumps and maybe add some color in the middle of it.
Won't be 5*, but a passable mainevent. Probably have Goldberg stay in the ring to milk applause if there is any, and if they want, have someone come out and attack Goldberg for heat.....Could be Brock's next opponent or random heel.
