LOL, hey now, I really really liked my aqua C remora, did an excellent job on my tanks.
My opinion, for what it's worth, is to go with the 10g sump and use a filter sock, and an in sump skimmer. i would pass on the refugium and/or scrubber.
I have a similar issue with my 60g cube, I needed a sump that wasnt over 23 inches so what I did was get a 16g tank which holds 50% more water which is a good thing I might add. I currently have an eshopps psk 150 and a biopellet reactor going in the 16g sump as well as a small filter sock to catch the floaties from the tank.
Also, to use an in sump skimmer you usually need to have maybe 7-9 inches of water for it to run.....in a 10g that would put you at the top of the tank and not allow much room for water from the main tank when you shut down the system.
Just some more food for thought!
