As far as patch ideas, you and I probably have very different creative workflows. We certainly have different modules. I'm not all that familiar with Hermod or SMR, so I can't speak much to the capabilities of those. I like a lot of repetition with subtle (almost imperceptible) changes, so I would probably be bouncing elements between Morphagene and Clouds in Looping Delay mode, subtle modulation, subtle addition and subtraction of elements, volume swells, happy accidents... kind of a musique concrete approach. I also like to add semi-random ratchets to a repetitive but slowly morphing 8 step sequence over another sequence of, say, 24 steps, and another element of, say, 36 steps for kind of a Tangerine Dream vibe. I don't know if Hermod can do ratchets though.
Do you have an external drum machine? Sometimes starting from a skeletal percussion line will lead you to new rhythmic and textural ideas with the melodic voices.
If you are looking to do more generative stuff, you will probably want to add something like Triple Sloths, Wogglebug, or something similar. I'm a huge fan of Pamela's New Workout for syncing everything. Ochd is a cool little multi-LFO, Sequential switches and long envelopes/slow LFOs through modulated VCAs will lead you in some fun directions. I've held off on picking up uO_C (Ornament and Crime) because off the menu-diving, but something like that or a Disting Mk4 might give you some options too.
It's hard to fit everything you need into a small case. I would recommend expanding, as Lugia mentions, to fit in all of the utilities and modulation you need before you sell anything. You have the big pretty modules and aren't getting the most out of what you already have. On the other hand, don't be embarrassed of buyer's remorse if you know a module isn't working for you. Sell it for a small loss and move on quickly to something that will inspire you for years to come. Just do your research first so those mistakes become fewer and farther between. Above all, have fun with it.
