Can I add coffee after carbonation?

[WoweeZowee]

The thread title says it all. Can I add coffee after carbonation?

Here's the situation. I want to add a pint of cold press coffee to a porter I made recently. I have two cornie kegs full of the same porter recipe. One of them is already carbonated and has a FG of 1015. The other has not been carbonated and has a FG of 1010. I want to add the coffee to the 1015 to closer match the gravity of the second batch. I usually shoot for a FG of 1012 with this recipe.

Thanks in advance
