Can you paste a link of the system rather than just a JPEG? I'm having trouble identifying some of your modules and it's much easier to calculate available rack space. On first glance, your system seems to have most of the core elements. Where are the envelope generators? Is there a filter... filters? Also, you can upgrade the Batumi with the Poti expander. It's around $60US and well worth the extra 3HP. Post that link and I'll take another look.
