If that would work, I would have made those bindings a long time ago.
However, on my terminal Ctrl+Backspace produces 0x08, which is the
equivalent of ^H.  We cannot rebind ^H to something else, it must do
a backspace as long as the user doesn't rebind the keystroke.

But you are right, we could at least bind Ctrl+Del to cutwordright
instead of leaving it an unbound key.  In the sample.nanorc we can
then suggest that the user binds ^H to cutwordleft so that Ctrl+Bsp
deletes the preceding word.

See https://invisible-island.net/ncurses/ncurses.faq.html#modified_keys.
According to the second table, you should ask for the code for kDC5.
