This would be a fun rack to play on. Since we are ignoring the 'start' slow advice... how about looking to getting a Vostek Atlas and/or a Dual Dagger ;)
I personally dislike 2hp (width, not the company specifically) devices. Just don't like the clutter... and as you said, those gaps will go away with the purchase of a module or two.
I think in general if you asked a more specific question, you'd get more specific answers. I can't say anything is wrong with 'your' setup... but I definitely have chosen very different modules than you.. Since you aren't wanting to start slow... what other modules have you considered? What are you on the fence about?
