Interessting challenge. Here we go:

fun! s:GetOffset()
let offset=''
let char=nr2char(getchar())
while char =~? '[-0-9]'
let offset .= char
let char=nr2char(getchar())
endwhile
return [ abs(offset+0)*-1, char ]
endfun

fun! s:LastChar(offset)
if a:offset[0] < 0
echomsg a:offset[0] . '|' . a:offset[1]
return string(virtcol('$') + a:offset[0]) . '|' . a:offset[1]
else
return '$' . a:offset[1]
endif
endfun

onoremap <silent> <expr> $ <sid>LastChar(<sid>GetOffset())

regards,
Christian
