If the answer is not (I think so), then I suppose the way is to create a new custom column and to copy old values from the other. In this case, is there any way to copy the full column (for all the library) at a time?

I think
this might work with a composite column:
Do the
Shell game with Search and Replace:
Make your new column (you can rename later).
Now select all books that us the custom column
Tap the 'E' key (bulk edit) and select the Search and replace tab
Select your old column to find
the REGEX search term is (.+)
Select your new column as the destination
the REGEX value is \1
Apply
Once you are happy, use the column editor to remove the old column
