I have the BitBox. I also like that it has two alternative firmwares that allow it to be a wavetable synth or a multi-effects box.
The ER-301 and Assimil8or are good choices if price and rackspace aren't an issue.
How fast do the LFOs on the Hermod go and can they be reset or sync'ed?
A second case seems more logical as this rack is pretty much full. I'd find a big-o-rack and keep the Intellijel as maybe a core rack or your performance rack aka the rack where you sequence and control the rest of your system.

Bitbox sounds quiet interesting will definitely check some videos!
You can sync but don't need to the lfo has SINE TRIANGLE RAMP SQUARE S AND H so its pretty nice, it can go quiet fast in sync 128/1 and without sync from 0-200% about reset I am not 100% sure but I think you can do it.
Second case could be an option but I have a wooden case but for live I would prefer that it all kind of stays in one box, so I have to adjust a little bit.
Thanks for your feedback!
