\"Splitting\" a Steam Radiator

in THE MAIN WALL
I have one-pipe steam heat in my 50-year-old house. I am splitting the upstairs bedroom farthest from the boiler into two rooms. I would like to "T" the steam line that goes to the current single radiator to supply two radiators, one in each room. My plumber says you can't "T" a steam line.

(By radiator, I mean the kinds with a row of sheet metal fins enclosed in a metal housing, not the big cast iron radiators of old.)

There are 8 radiators in my house and not 8 steam lines leaving the boiler, so I know that radiators can share a steam line.

Can I "T" the steam line? What are the issues/problems?

Do I simply need to use a "Y" instead of a "T" so the water can run back down?

If I can't "T" the radiators, can I feed one radiator, then pipe out of that radiator a short distance through the wall into the second radiator, terminating that one in an air valve?

Thanks,
Dave

    Sounds to me

    that you aren't adding any radiation at all but merely splitting it into two half sized loads. Then you can T it. You should think about using a vent on each line that is of a "slower" rate (smaller orifice) since you will now have two vents on that riser instead of 1. This can change the system balance in a way you may not like. Or use the same kind of vent and see how it works. I'd say its a good idea to have the two vents identical, though.
