It's also going to be necessary to run all 8 wires from the bluesaab pcb to the legacy adapter; the legacy adapter will "pass thru" the car power, gnd, and i-bus connections.

Well that's a similar effort if you build a whole new passthrough adapter and attach a fly lead

I'm not convinced that using longer screws to mount things will be enough support for the connector. The bosses are only 1/4" high, and as it is now, the CDC is almost in line with them, which makes for great support. When you move the connector to go through a vertical screw mount and then push on the top, the boss's are not gonna hold that torque at all.

You could extend the screws through to the lid, and add nuts once the lid's on. Not as pretty, but probably still neater than adding a second box.

Or stick with option 1; it places the connector in the same relation to the bosses as the original.

Honestly, I would suggest the best way at the moment is to desolder the 4 speaker pins, bend them up and out, and then solder wires as necessary. Obviously you're still gonna need to solder 10 wires; 4 speaker in, 4 speaker out, and 3.3v and gnd to the amp pcb. it's a lot of work.

If people want, I can post the pcb as-is, and they can go the heat shrink method...or we can brainstorm some more...or people can just make a v5.0+ module

I assume the fully external module with connectors will appeal to people who got their modules from someone else and just want a plug in. Whereas if I had an earlier one, I'd be looking for a cheap in-box mod. In that case, I'd want the option 1 version that's wider, and the option to leave out the 3.3v components and bridge from the board. I wouldn't have an issue with soldering two ends of 9 wires.

Well I've been throwing out ideas to help reduce the costs, but I guess it really depends on people who actually have a pre-5.0 module and their appetite for soldering vs cost so I'll leave the conversation to them.
