If the series loop tubing is large enough to handle the flow at the distance

piping them as a series of radiation on one loop would work well. However, the radiation should be of the right size in each room, or oversized radiators in a room will overheat that room and can not be turned down without affecting the other rooms.
It would be better to pipe the system as two zones of one-pipe configuration

so you can close down individual radiators and use automatic radiator valves to control heat in selected rooms.
