You can use (let ((end (copy-marker end t))) ...), of course.
I don't find it cryptic at all, but I'm probably not well placed to judge.
In any case, my main point was that using narrowing can have undesirable
side effects because narrowing has a far-reaching impact on operations
in the buffer, so depending on what you need to do within your loop you
might prefer to stay away from it (unless this far-reaching impact is
exactly what you're looking for, obviously).
