My experience with coils in coal stoves is limited to heating domestic hot water.
The limiting factor with coils seams to be the limited surface area for heat transfer from the fire, it gathers heat but most heat passes the coils and goes into the room.
Coils will heat more hot water than I can use, but I doubt you will notice a reduction of heat from your stove due to the coil.
To answer your question, if your circulation pump stops the boiler could overheat, if the pumps keep working, no problems.
More advice will follow I'm sure.

The coils in the hand fired stoves are typically very short, 3 or 4 feet and just a flat surface. The typical setup is to use a thermosiphon loop to an existing hot water heater or insulated storage tank. It's a very slow action.

you couldnt put a big enough coil in the hand fired to do the job of heating the oil boiler and zone's water capacity..
you could heat the domestic part of it probably

you should invest in a stoker boiler and tie it into the system. use the oil unit when your on vacation or out of coal

just dont run out of coal

It's slow but it works, probably the bigger question is if it's worth the investment.
