If this was possible don't you think some chinese company would not be selling new lasers for us at half the price ?
The bad thing about the PS2 DVD laser is that it's protodiodes (the receiver part) is custom, due to the copy protecion sense mechanism They have a slightly diferent placement than standard lasers, which make difficult to use standard lasers on the PS2... Maybe with a lot of adaptation and a Modchip it would be useable...
