Could you add heads with mechanical t's instead of doubling up on the 1/2" outlets?

Looked at a retrofit job last week. It's about 15K SF of office area being cut up. The old overhead grid system is all done with 5' flexheads off 1/2" outlets with reducer bushings. I asked why they called me. They need to add more heads, can I do the same as what's there now? In some instances, there are 2 flexheads off a single 1/2" outlet. Just for giggles, I ran some quick hydraulics using the main drain data, 125 S, 110 R. Seems like what's there will work (even the doubles) mostly due to the 2" branchlines between the 4" crossmains. Many need to be moved, some added, some removed,.. Keep going?
