Problems with Custom Chips could be omitted by placing only sockets for it.
In that case customer need to get chips on his own or just take chips from old motherboard. Problem could be also to get DB23 connectors.
If enhanced, replacement motherboards of the kind you're talking about were to become available, then DB25 connectors would have to be used instead, and video cables and external floppy drives would have to be adapted to use them by replacing their DB23 connectors. That would be a relatively small concession to make in order to use such hi-spec motherboards.
