20 gallon is a very small sump, I would drop one of the baffles. Probably make the return and refugium area one section and have the skimmer in the return section.
I personally would look for a bigger tank to use as a sump. Lots of people give away tanks that are perhaps scratched or otherwise cosmetically challenged that are perfect sump tanks.
I know you said your using the remora skimmer but always be prepared for the eventual upgrade.
