What is the total cost for a pcb populated with components? Probably around 60-70 qty 100?
I appreciate the blog post and the writeup, it might be nice to include it in the repo.
I have been toying with a similar design, with many of the same choices. Although for the system controller pair, I'd go with RP2350B and ESP32-C61 (I think). It would be nice if there was an optional chip and pad layout to support legacy or classic BT.
It looks like supporting legacy BT while noble, could be a project killing sidequest (if you didn't already have it done!) Another out, would be exposing an SPI connection internally so someone could hack in a controller of their choice.
Populated PCB in quantity 100 would probably be 60-70 USD, yeah. Maybe a bit less, it really depends on how much you can buy the FPGAs for.
I really did want to switch to the RP2350B, but it's (still) not available to buy. There's also the (unreleased) Raspberry Pi RM2 module which would help with Bluetooth Classic and LE support.
On Game Bub, I do expose a Pmod interface (4 data wires) connected to the FPGA, so that actually is an option here too.

Another option would be to have a USB port and support something like https://www.8bitdo.com/usb-wireless-adapter-2/ to enable legacy controllers.
