Too many baffles in AquaClear 70 refugium mod?

Hello everyone. I recently picked up an AquaClear 70 which I have been working to mod into a HOB refugium for my nano reef. This is a pretty common mod but most of the tuts and forums have people modding the AC70 with only a single or double chamber for chaeto, live sand and maybe a heater. Technically, my mod would have 4 chambers, in order: 1- Intake/filter cartridges, 2-Heater, 3-Macroalgae/Chaeto chamber, 4-Oceanic Biocube Mini-Skimmer.

The baffles would be acrylic the same way this guy designed his: http://reefcentral.c...t=how to DIY an

Can anybody see any problems I would face with this design? It is a lot to fit into a small space but physically, I can fit everything cleanly. Any thoughts or suggestions? Thanks in advance!
