Possible…probably. You would have to get a parts diagram of both units to see if you can cross-install the required igniter board, igniter/thermocouple and a new solenoid controlled gas valve. 12VDC would also have to be provided for the igniter board's operation, as would a control switch.
Cost effective……probably NOT. In your situation, I would get a new DSI water heater (with an electric element also) AND a new 2 year warranty. The parts required for such a project will add up and closely approximate the cost of a new complete unit.
PLUS, if you are not intimately familiar with working with LP gas components and 12VDC, I would strongly recommend against it!
