Well, in theory it is, but it would require a lot of mappings (at least
52 of them).

I am currently compiling a Russian-French dictionary from four existing
ones, which means that I often have to switch between Cyrillic and Latin
in the middle of a line, sometimes of a sentence. I use a keymap which
suits me, and in addition the following mappings:

:noremap <F8> :let &l:iminsert = ! &l:iminsert<CR>
:inoremap <F8> <C-O>:let &l:iminsert = ! &l:iminsert<CR>
:cnoremap <F8> <C-^>

and the following 'statusline', whose relevant part is the presence or
absence of the keymap name as the leftmost item in the righthand group
(the %k item immediately after %= ) :

" custom status line, see :help 'statusline' for details
if has("statusline")
set statusline=%<%f\ %h%m%r%=%k[%{(&fenc\ ==\
\"\"?&enc:&fenc).(&bomb?\",BOM\":\"\")}][U+%04B]\ %-12.(%l,%c%V%)\ %P
endif


This way, hitting F8 in any mode toggles between keymap active
(Cyrillic) or inactive (Latin), and the corresponding status is shown on
the status line. In Normal and Insert mode this also switches off (IIUC)
any Input Method which might be active previously (for CJK etc.).


Best regards,
Tony.
