Tested with snapshot 20w18a - will test again when 1.16 is released formally.
All the timings are copied from Gnembon's design: youtube.com/watch?v=XQCc7QywrCI
The difference from Gnembon's design is that target blocks are used to turn on and off hoppers, rather than feeding signals from repeater/observer/rail combinations.
This means that we have half the number of dropper towers horizontally, but also reduce the resource cost to build and the depth from front to back. Personally I prefer to have gaps between my dropper towers so that my item frames are on blocks rather than chests, but that is a personal preference.

This isnt a complete design... but its about as far as Im going to take it and should still be useful for someone out there.
Basically can have up to 14 brewing stands, each with a separate (or same) recipe going, on repeat, as long as the chunks are loaded - there is overflow detection to stop the system if any chests fill up (or water bottles run out), but do need to make sure any active towers are set up to make the same number of potions as otherwise will just brew water potions on the towers that are short. Although these can be manually fed back into the system
Each individual brewing station can also be disabled if a 14 brewing stand system perhaps only wanted to be run with 3 for a given run.
I still havent worked out the right way to start up or shut down the system without wastage - although I recommend only disabling or enabling towers while the system is completely idle (unlike what I did in the video). There is a prime switch that can get it going once enabled - although there is some finesse needed here as well.
Also some apologies, I reference the inspiring design as gnembons a couple of times in the video - but I meant to reference ilmango.")
