Hi,
welcome! I'll start by asking: are the two hermods a mistake, or were you planning to put both in your rack?
Secondly: do you plan to use eurorack on its own, or in conjunction with your other gear? If so, I think hermod is unnecessary if you plan to use it as a simple midi to cv converter. It is an extremely powerful sequencer, but it's overkill if you only plan to use it for conversion for sequences coming from live/other external devices.
Lastly: do you also have an outboard mixer, or other gear of some sort that you can connect your modular to and bring it into your daw (that also accepts modular level)? If not, I think an output module is also needed.
What you have shown here is absolutely enough to begin your journey. What is and is not interesting is extremely subjective, especially in modular land. Personally, I would add another simple basic analog oscillator, and some more hands on modulation/random. A turing machine and/or the simplest step sequencer you can find. For me, especially in modular land, interesting is very often closely related to unexpected. That's when modular is not a collection of modules, but becomes an instrument in the more traditional sense of the term: something that you have a conversation with, and it has to be able to talk back and not just execute instructions.
