It's possible but not worth doing that because, then, the
rest part is very small as I wrote below.

Yes. And if we setup all information in
char-coding-system-table, loading of coding systems is
almost finished. The biggest part of coding system is a
mapping table, and without mapping table, we can't have a
complete char-coding-system-table.
By the way, when we shift to Unicode, the situation gets
more difficult, because we must have lots of mapping table
for such legacy charset as latin-X, JIS, GB, KCS, etc. (As
I wrote before, in unicode base Emacs, mapping table should
be for charsets, not for coding-systems). Anyway, I think a
practical solution will be to give up checking all possible
coding systems in find-coding-systems-region, but checking
only these:
o buffer-file-coding-system
o several commonly used ones
o what specified by the current language environment
o what a user requested
