I'd would suggest Tetenal to make the 5L kit again, including a mini Protectan can in the kit, with proper preservation instructions.
Nothing wrong with an additional 5L kit in the mid-term. But Tetenal would then compete with the excellent Fuji Hunt 5L kit, which is offering perfect quality and the lowest development cost per film.
The bigger and more attractive market gap is currently in the lower volume consumers group: Lots of new color reversal film shooters lately, but most of them are using not more than 10-15 films p.a.
For this customer group the reintroduction of the former 1L kit would be perfect. Two years ago at Photokina (before their insolvency) Tetenal said they are thinking about it, offering the 1L kit again. Would make sense to reconsider it now.
It is well stated that the E-6 concentrates can keep well for a year if protected with preserving gass after opened, I've done this many times: mixing what needed and gas-preserving the remaining concentrates.
Shelf life of E6 chemicals can indeed be significantly extended easily and at negligible costs by using Protectan and glass bottles (after opening the original concentrates for the first processing). I am also using different sizes of bottles so that over the time the bottles are either completely filled, or only a small space must be filled with Protectan.
Best regards,
