Probably not, since spell vamp doesn't proc from his W. Lichbane would be pretty powerful with his ult's low cooldown or Voidstaff and Madred's to improve his HP shredding abilities.

So part of the tradeoff with Kog'Maw is that you won't be auto-attacking much when you're R spamming. I wouldn't grab a Madred's Bloodrazor in this case, or if I were, I should have went hybrid/AD Kog'Maw. Not to mention Live Artillery has MUCH longer range than his Bio-Arcane Barrage. Distance is a pretty nice means of safety, and Kog'Maw really excels at that. In my experience, people would love to shut you down if they get the chance.

The deal with Gunblade is that it contributes the most to R damage in a single slot (actually Rageblade does, but it needs stacks to be effective). The lifesteal/spellvamp is icing on top, and the slow active can help to peel off the occasional gap closer champ. The main issue I see is that it's pretty costly.

Now that I've done more thinking, I probably should get Lichbane + Voidstaff combo instead. MS is pretty invaluable for a kiter (I had Ghost that time, so if Skarnerssss tried to surprise buttsex me, he's going to have a really hard time catching me), and sporting +600 AD to auto-attack per proc is nothing to scoff at. The base damage on R is pretty high for a poke (400 magic damage versus champions), but it scales really badly. Not to mention the other abilities do benefit from AP (no AD scaling), and Void Ooze has a decent range for poking and keeping them at bay.
