Yes, it is possible. Here are the steps:
1. Install vim-addon-manager:
http://www.vim.org/scripts/script.php?script_id=2905
2. Put the following into .vimrc:
let g:vim_script_manager={"plugin_root_dir": expand('~/.vam')}
try
call scriptmanager#Activate("SuperTab_continued.")
catch
endtry
" Assuming that <Tab> is remapped in normal mode:
let s:map_tab_supertab = maparg("<Tab>", "i", 0, 1)
let s:map_s_tab_supertab = maparg("<S-Tab>", "i", 0, 1)
function s:GetMapCmd(mode, noremap)
let cmd=((a:noremap)?("nore"):(""))."map"
if a:mode!=#'!' && a:mode!=#' '
return a:mode.cmd
elseif a:mode==#'!'
return cmd.a:mode
endif
return cmd
endfunction
function s:RestoreMap(exmap)
if empty(a:exmap)
return
endif
let exmap=a:exmap
execute s:GetMapCmd(exmap.mode, exmap.noremap)." <special> ".
\((exmap.buffer)? ("<buffer> "):("")).
\((exmap.silent)? ("<silent> "):("")).
\((exmap.expr)? ("<expr> "): ("")).
\exmap.lhs." ".
\substitute(exmap.rhs, '<SID>', '<SNR>'.exmap.sid.'_',
\ 'g')
endfunction
inoremap <S-Tab> <C-O>:call NextField(' \{2,}',2,' ',0)<CR>
" I do not find mapping to tab in that tip. Put it here
let s:map_tab_nextfield = maparg("<Tab>", "i", 0, 1)
let s:map_s_tab_nextfield = maparg("<S-Tab>", "i", 0, 1)
let s:next_map="nextfield"
call s:RestoreMap(s:map_tab_supertab)
call s:RestoreMap(s:map_s_tab_supertab)
function s:AlterMap()
call s:RestoreMap(s:map_tab_{s:next_map})
call s:RestoreMap(s:map_s_tab_{s:next_map})
if s:next_map is "nextfield"
let s:next_map="supertab"
else
let s:next_map="nextfield"
endif
endfunction
command -nargs=0 AlterTab call s:AlterMap()

3. Start new vim, answer yes on all queries.
4. You can now alter <tab> and <S-Tab> behavior with :AlterTab.
