As physiculus apparently uses a linux system, I assume, that 
"find" will be GNU "find", "ls" will be GNU "ls", and a "bash" 
will be available. 

   (
     cd -- /the/nndir/directory/hierarchy &&
     find . -depth -name '*!*' \
       ! -exec bash -c -- '
         curname="${1##*/}" && dir="${1%"$curname"}" &&
         newname="${curname//!/:}" &&
         if test -e "${dir}${newname}" ||
           test -L "${dir}${newname}"
         then
           # The file to be renamed to already exists!
           # What should be done?  Let the user decide:
           cd -- "$dir" &&
           printf %s\\n \
             '\''current subdirectory:'\'' \
             "$dir" \
             '\''The file to be renamed to,'\'' \
             "$newname" '\''already exists!'\'' \
             '\''Please enter shell commands to resolve'\'' \
             '\''that situation.  For your convenience,'\'' \
             '\''the current file'"'s"' name is in the'\'' \
             '\''positional parameter "$1", while the new'\'' \
             '\''one is in the positional parameter "$2".'\'' \
             '\''For example, try the commands'\'' \
             '\''  ls -QF1logd -- "$1" "$2"'\'' \
             and \
             '\''  mv -i -- "$1" "$2"'\'' \
             '\''Type the command "exit" when finished.'\'' &&
           ls -QFlogdU -- "$curname" "$newname" &&
           "${SHELL}" -sim -- "$curname" "$newname"
         else
           # REMOVE THE FOLLOWING LINE STARTING WITH "printf" TO
           # ACTUALLY LET THIS COMMAND MOVE FILES:
           printf '%q\n' \
           mv -- "${dir}${curname}" "${dir}${newname}"
         fi' bash \{\} \;
   )

Not tested, though, therefore the actual "mv" command will only be 
printed rather than executed.  See the comment written in 
capitals, above.
