plumbing plan on 3" stack

Im finalizing my plumbing for my workshop, I’ve got a 3" main drain and planned 3" wet vent for the plumbing. The sketch is my current plan. The lowest two "entrances" on the stack had to be reducing combo sweeps in order to clear the purlins and stay low to the slab; though I suspect santitary-tees would be called out if it was a continuous 2" pipe meeting a 2" pipe.

So my question is: have I selected the two red long sweep wyes correctly? Side to side this whole contraption is about 12′, so it is very tight. Blue represents 3" ABS, Black 2" and green is 1.5" primarily for vents. The Dual-sanitary Tee in the middle can have a vent line tied back to the main stack if that is required, but it is not shown and otherwise it will be caped. It sits about 1 foot from the stack.
