I imagine BotRK, Wit's End, Zerks, Cleaver, and Runaan's will all be good as new items for this guy, plus one more AS item if you somehow haven't reached 2.5 yet (maybe Shiv since I think you stack it fully in 2/3 of a second with Runaan's  + 5.00 AS), or more likely a third and fully defensive item like GA or Banshee's. With max AS during W and Runaan's, you get max MR steal and max Armor Pen from Wit's/Cleaver on 3 enemies simultaneously in just one second, and the other choices (Zerks and BotRK) are quite self-explanatory.

I personally think Rapid Firecannon isn't as useful as it seems. You gain extra range but its limited to a 150 bonus and only works for one attack. Maybe if RFC worked for 1 second after the affected attack it'd be better, but that would probably be too OP on Kog to ever happen.
