The take-offs don't matter much. It is a matter of separating out the liquid water and letting it drop back into the boiler. That is done by vertical rise, direction change and volume increase (larger header) that causes the steam to slow. Liquid has mass and thus momentum (mass x velocity), unlike the steam. I would be more concerned about your bldg being big enough for 5" mains and if the boiler and number of 3" take-offs are sufficient.
