External Heat Exchanger?

I'm trying to convert two separate domestic hot water and space heating systems into an indirect system. Currently, the water heating system consists of a Laars Teledyne Mighty Therm Volume Water Heater, heating water in an AO Smith TJV-120M storage tank. However, the storage tank does not have a coil, so it cannot be used as is in an indirect system. I emailed AO Smith and asked whether or not it was possible to simply open the thing up and put in a coil. They replied saying that this was possible, but that it may be more economical to install a heat exchanger outside the tank. I don't have a clue how this would work. Does anyone know? Thanks in advance.

P.S., the space heating unit is a Weil McLain LGB-9 steam boiler, which will provide the hot water in the indirect system.

you could add a brazed plate heat exchanger, a bronze circ for the domestic side, and a CI circ for the boiler side.

Not sure how great of a solution it is, there is going to be lots of heat loss around the heat exchanger and pipework to deal with.

Its def. possible though.
