Blocklet to cycle through multiple blocklets configurations

[Aster89]

Since my screen is quite small and the number of blocklets I'd like to use is large enough, I think that it'd be nice to have a blocklet which allows to cycle through a list of different configurations of the i3blocks bar.

For instance, if the bar initially looks like
(cycle through bars(disk space(battery(ddmmyyyy(clock|
clicking on the "cycle through bars" blocklet could transforms the bar to
(cycle through bars(spotify(wifi(arch update(volume(keyindicator|
Clicking again could change it to some other configuration.

The most obvious way I think of in order to achieve this, is to have a blocklet which, upon click, really edits the ~/.config/i3/i3blocks by means of (the simplest think I can think of) a sed script which exploits some comment placeholders in that file.

Actually another strategy could be that ~/.config/i3/i3blocks be a symbolic link to one of the actual configuration files, and that this new blocklet simply links the link to successive configurations file in cycle. I think this would be faster, but would mean code duplication (since I could want to have the clock blocklet in every configuration).

Can I have some opinion about this?
