this  may be something for kiosk?

also this may be supported by kiosk?

Hi,
I think all of this can be done by providing a custom "look and feel" package,
with a layout.js script. Even if the details of it are not complete yet, 
should already be possible to set the theme, plasma and widgets, wallpaper, 
and menu icon

Like
https://quickgit.kde.org/?p=plasma-workspace.git&a=tree&h=39b9af963eeb5ecea0a00c23280bef20aeeec840&hb=312f1e250202f705b8a216b86a4c320ec33b16a9&f=lookandfeel

(discarding all the subdirectories containing qml files)

on first startup when the layout.js gets executed you don't have to remove 
plasmoids: you have an empty setup in which you only add what you need.

in order to do tests, is convenient to use the interactive scripting console 
by launching

qdbus org.kde.plasmashell /PlasmaShell showInteractiveConsole

even tough it will be a slightly different situation as you have a complete 
setup already.

(in order to make this sort of things easier i'm making a tool that will 
create a look and feel package based on the current plasma layout, but will be 
available from 5.8)
