-HDMI + embedded audio would add a lot of cost, and there are many ways to accomplish this, some of which sucks. Maybe leave this out to reduce cost and let people choose a conversion solution that works best for them.
I've got a solution that should run ~25$ in parts.
What do you think about Component outputs instead of hdmi?
I'm looking at some kind of video conversion, because neither 15k and VGA are that great to integrate with a modern home theatre system.

-USB decoders for modern controllers would again, add some cost and there are many way to accomplish this some of which suck. Maybe you could pick a popular usb encoder product and provide a pin-header installation for it that would make it easily expandable while also reducing the costs for those who don't want/need this
I was considering implementing a basic HID adapter on this thought process- a modern USB arcade stick or gamepad would work, as will just about anything that can be converted to USB.

-"Walsdawg standard DB25 controller ports (easily adaptable to DB15 joysticks)" - why not just use DB15 joystick ports?
Because Naomi uses Analog on a lot of games, it would make sense to keep this capability, no?

~"Either a Sega JVS board Type 1 would be condensed down to fit directly on the board, with a socket for a donor 315-6291 chip, or a JVS IO replacement would be used." - that seems way too complicated. We have the OpenJVS project which uses an ATiny to function as a JVS I/O board, why not just use that? you'd be looking at $2-$4 component cost and an extremely compact solution build right into the filterboard as opposed to hacking up or trying to squeeze a $100 I/O board on this thing.
Right now, analog support via OpenJVS seems .... nonexistant, but if it can be made to work I'd be totally onboard with using that instead of the official IO
Also, the currently rising prices on the Type1 IO are problematic for that route- this is why I was looking already at going with OpenJVS or similar.

~"Internally mounted Raspberry PI + LCD menu for game selection" - i'd suggest just having a GPIO/Ethernet pass-through on the filterboard so that you could mount the Pi internally and then plug the pi-plate onto the filterboard from the outside, similarly you could get a pin-header extension cable and remote mount the Pi plate somewhere if you didn't want it attached directly to the NAOMI. this would meant that the Pi would remain separate from the filterboard, again just for those who want it and greatly simplify the integration. Some people will want to continue using carts or SD cards.
I was thinking to utilize an RPIZero mounted to the inside of the filterboard, with the LCD and keypad for it mounted on the outside.

-a proper power switch
-a proper reset switch (for when net-booting gets hung up)
-dipswitches for region and resolution selection clearly marked on the filterboard itself
-serial ports for card readers or some kind of integration for winteriscomming's card emulator.
DEFINITELY to all of these- that was somewhat given- with putting the PSU internal, having the power and reset switches included makes perfect sense.
I'd also prefer to use either smallish toggle or at least levered DIP switches to make switching them easier.
I was thinking to retain the MIDI and RS422 pin headers from the original design.
I know this sounds like a lot of defense on my part, I just wanted to explain where I was coming from...
