If things are still exposed you may just want to bite the bullet and get a purpose built unit like the Reznor.
You're going to all the trouble of running a line, ducting, electrical for this house furnace that may: fail soon, fail inspection, and is not designed for that use case. I'm sure it would work, but thinking of passing inspection with requirements around cold air returns, sizing, etc, just gets questionable.
A tonne of the costs will be the same between furnace and Reznor options, but this way you're not doing it twice (if it dies or doesnt pass inspection). Which could be really costly if you end up having to rip finishings out to run a gas/electrical/duct lines to the roof unit the second time.
Plus you'll free up floor space without a hunking furnace and duct lines on the shop floor.
I've got an older wall mounted unit (vents out at the top of wall like a sealed fireplace). But I'll be damned if a heated garage isn't the cats meow.
