Yes, this will work. The ccvm head dose the vapour split based on the pipe sizing at the branch, the column underneath could be any diameter in that respect, provided the condenser is up to providing enough reflux.
With the 3", If you run at the same power level as the 2", you will get a slightly more pure product, when you add more power, you will loose that purity bump and it will run faster. This is all at the same reflux rate, the other option with the 3" is to keep the power the same and reflux less. You would have to drive the still a bit to see how you like it either way
In either instance more height will help, the 2" can run faster if there is only 1m of packing there now, another 60cm or so would make a dramatic difference - you end up needing less reflux to get up to the same abv, freeing up vapour to be turned into product - speed
