Post filtering cocoa powder question

[SouthBounds]

I have a great chocolate stout on tap. Problem is, I didn't get all the suspended cocoa powder out of it. It kind-of ruins the mouthfeel of the beer.

I ran a sample through a mesh filter and it worked beautifully. Question is - how would you recommend filtering 5 gallons of carbed up beer?! Rack it through a filter to another keg?

You'd need to do a closed transfer through a filter using pressurized co2 to avoid oxidizing the whole batch...something like this:

Fining with gelatin might work.
