I love this idea...
However, I've never played around with Systainers soI have the following two questions:
1) How easy is it to swap the lid from one Systainer and put it on another (without breaking)?
2) How easy is it to swap the lid latch " " " .... ?
Since it looks like the Lee Valley Attic Systainer has a blue lid latch, I assume you swapped both the lid and the latch (to keep the Festool Green look).
p.s. In addition to expanding the storage of the Centrotec Installer Set, I'd like to do this for my Carvex Systainer and put the saw blade storage in the Attic....
