If the wood stove causes a creosote fire, the coal stoves baro-damper will open and send a rush of air (oxygen) to the creosote fire just when you will need the opposite thing to be happening.
You could cap the baro, say with heavy aluminum foil, when using the wood stove. Still might not be legal, but if you are conscientious about doing it, that avoids the creosote fire problem.
Oops! I take it all back. A creosote fire could conceivably happen while you are burning just coal, with the baro unsealed. And that could happen even with a separate connection of the coal stove's pipe to the chimney, unless you clean the chimney after burning wood and before switching to coal.
One other point -- I don't want to rain on your parade -- you want to use the Mark I for colder days, but its realistic sustainable heat output is no higher than your Resolute, probably less, in spite of its slightly higher manufacturer's rating.
