Rebuilt our kitchen in a mid-20's bungalow. HOt-water [not steam] boiler with separate supply and return piping - the guy that built the house had more money than sense. That was one wonderful heating system. Even had 2 large radiators mounted flat, suspended from the joists below the living room floor - radiant heat.
ANyway - traditional cast-iron radiators all around.
One in the kitchen on the bottom level of cabinets. I made a "louver" for it, if you will. IIRC, it was a bunch of 1-1/4" x 3/4" slats, lap-jointed all over the place, with "holes" maybe 1-1/2" square. Installed with some rare-earth magnets that hit some target - forget what I used for those metal plates? YOU don't need a lot of magnet strength - the panel is not going to want to go anywhere unless you yank on it.
Really easy to do. ONly issue, of course, was the jillion lap joints - panel was maybe 30" x 24".
Air moved from radiator out the panel via convection just fine....I did add a piece of thin brass sheet above the radiator - kind of a curved fairing - to direct the rising heat to the front.
You can't possibly cause any material inteference to the air flow of your ducted system. That would be the farthest worry from my mind.
When I started woodworking, I didn't know squat. I have progressed in 30 years - now I do know squat.
