Modular CCVM build

[Sk8brew]

I am starting a CCVM build for neutrals, mainly to make gin, and am looking for some advise. I currently have the setup shown below with a 10gal boiler that runs 2800W max on 240V. It has double walls to provide some insulation. My current potstill is a 2" column with a 1" over 3/4" Liebig condenser. I am looking to build a CCVM and would like to make it modular so I can use the PC for both columns. After much research, here is what I am thinking:

The boiler has a 2" cap soldered to the SS lid. From here I will use a 2"-3" reducer to a 3"SS column. The top of the boiler is 32" and the ceiling is 88". I think this gives me room for a 3"x40" column, leaving 16" for a 3" Tee and condenser above the tee. Is this enough?

On the output side of the Tee, I need to reduce down to connect to the Liebig. I could either do this at the 2" region or 1" region prior to the elbow, or to the 3/4" union. I am not sure what length is needed from the takeoff at the 3" tee before reducing down. My plan is to put a tri-clamp fitting in here to make it easy to switch columns (unless I connect to the union). Thoughts?

I posted in another thread, but will put it out here too. I read that for a 3"column, 3000W is needed. My boiler is 2800W. Will this be a problem, or is it still better to go with 3" than 2" to increase output rate?

Thanks for your help!
