If you make the rack public then other users can viez it properly and get click through and infomatics - really useful when helping!!!
You need more vcas - get a quad cascading vca - mutable veils or intellijel for example - I'd also consider replacing the tallin with the intellijel 1u vca - all of these are dc coupled - as are most vcas
How are you mixing? if you do not already have an external mixer - you either need to buy one or put one in the rack - even if you do have an external mixer you will need sub-mixers, panning, modulation
Some utility modules will massively add to the variety of patches that you can create - mutable links, kinks and shades for example
you will need to free some space to accommodate these modules - the erbe-verb seems to be the obvious sacrifice - too big, not really a generic end of chain reverb (which is possibly what you are after) - replace this with an FX Aid XL and it will free 14hp more up - this may still not be enough!!! next to go would be the mimeophon (you seem married to the erica stuff) and again replace with an FX Aid XL

Utility modules are the dull polish that makes the shiny modules actually shine!!!
