I would like to make a system that pulls outside air for combustion, and
just heats the room without using room air to run the stove.

I've heated with wood for 58 years now. I think a good heat exchanger
is more important than outside air source for a shop, you need a few
air exchanges anyway. That said, my house heat system uses outside
air.

You can buy a wood stove cheaper than you can make one. But I made
mine with a very simple efficient design. It uses two barrels, lower
chamber is fire box, upper for heat exchanger. My "barrels" were
actually 24" diameter steel pipe. Then a large sheet metal plenum
around the whole thing and a furnace fan.
