Unpopular opinion - Riser venting > Main venting?

I have one 4 story building with no main vents but has 2 risers, front and back, supplying all the heat, and they are tapped and vented. The riser gets hot in 5 mins from the header, and the radiators are hot in another 5-7 minutes. Compared to other properties that I installed a big mouth on, the main gets hot in 2-3 minutes, but it takes another 10-15 minutes to reach the top floor.
The clear answer seems to be to vent these risers as well. This leads to my second question, can i avoid tapping the risers and just tee off the last radiator on the run with a 1/8 tee and add two gorton d? Can the last radiator on the line vent too fast?
