Definitely, it’s a great idea!

The ‘wrap-containerized’ procedure above wouldn’t be hard to write
((guix scripts pack) has something similar).  It could use a trick as in
<https://lists.gnu.org/archive/html/help-guix/2018-01/msg00118.html> to
automatically determine some of the default file system mappings.

The next step I think would be to make a package transformation option
for that, so one could say:

  guix install eolie --contained=eolie

or similar.
