You can.

Barrels ignore 60% of the armor. I believe it stacks additively with other forms of penetration. You can get LW, Bloodthirster and Mercurial Scimitarr along side TriForce and Ionian Boots and you will deal almost the same ammount of damage.

The thing about crits with GP is that it can splash all around the area of the barrels and you can get a whole lot of damage from it.
