Thanks for the detailed responses KL.
There's no particular component that I feel I need specifically replicated (although I really don't like the idea of a 3" butterfly valve for controlled dumping), but having adapters top and bottom to a standard fitting (tri clamp specifically) allows so much more interchangeability with the drawer full of parts that a lot of brewers have. Certainly having first-party solutions to common components and processes is worthwhile and make sense for the new brewer, however as an example I personally already have a stainless unitank and two drawers of components that make much more sense to be able to also use on a potential FermZilla rather than having to start from scratch. A few specific components for me are that I like to have the option of using different types of dump valves for different beer scenarios (heavy or no dry-hops, yeast collection or not, trub dumping or not, set and forget) (butterfly, diaphragm, encapsulated ball), reducers, elbows, spool extensions, CIP connections (hoses, reducers, barbs), 1-wire sensors, carbonation stones, tee-pieces to add more ports, etc. etc. etc. I already own one of your 4" kegmenter caps for use on the unitank, and would do so on a FermZilla also in conjunction with other components.
Rather than trying to get a KegLand solution to every specific use case I'd love to see two simple adapters (or maybe three, if you did both a 2" and 1.5" version of the cone adapter) that open up the whole world of tri clamp components (not precluding development of those KegLand solutions also...). I guess some sort of disclaimer or voiding of warranty around over-stressing the body by applying a torque on the cone base with parts hanging off an elbow would be reasonable given that at the end of the day it's not a stainless unibody vessel. The top adapter could just be a replacement end cap with a 4" port that fit under the existing lid ring, or it could be a one-piece threaded replacement I guess.

Fair enough re the stand, given that a pre-defined "short" stand is not likely to match everyone's preference either. Some sort of stand that was the same as the current one but with lugs on the top ring rather than legs would be great so that it could be suspended off any given set of legs or a hole in a timber shelf, but maybe there are issues around leaving the engineering (or lack of) to the end user and risking dropping 30 kg of fermenter on their foot... Custom solutions (the fermenting fridges) are awesome but not everyone is able or wants to replace existing equipment.
) and might even consider moving on my stainless unitank (edit: no that's just silly...). Have you confirmed whether you'll be making a heat-tolerant body available or not? For what it's worth, I vote yes...
