The problem is, how does one achieve that? On slimlines, there isn't an external expansion connector anymore. Perhaps something can be done if somebody taps onto the expansion connector which is located on every PlayStation 2 mainboard, but a lot of work will have to be done because nearly nothing is known about that connector.
