Can you crossfire with different memory?

Hi,

I'm planning on Crossfiring my MSI R9 270X 2GB soon with another MSI -- I want to keep in the same brand just in case there are any firmware upgrades -- but looking in Newegg and Amazon, it seems to be easier to find an MSI R9 270X "4GB" version than a "2GB" version one. So will the 2GB version work with a 4GB one? Or would it be better to just get a different brand with the same memory? Please help! I've searched online already but haven't really found anyone with the same question.
