I'd say no.  `C-x r' has a mix of different kinds of commands
(bookmarks, registers, rectangles), and it has had such a mix
since about forever.  `C-x r' is not the place to be defining
alternative keys for the same command, IMHO.

(It's bad enough that we have three keys for `point-to-register'.
But those alternative `point-to-register' keys have been there
since at least Emacs 20.)

This is what `C-x r C-h' shows:

C-x r C-@	point-to-register
C-x r ESC	Prefix Command
C-x r SPC	point-to-register
C-x r +		increment-register
C-x r M		bookmark-set-no-overwrite
C-x r N		rectangle-number-lines
C-x r b		bookmark-jump
C-x r c		clear-rectangle
C-x r d		delete-rectangle
C-x r f		frameset-to-register
C-x r g		insert-register
C-x r i		insert-register
C-x r j		jump-to-register
C-x r k		kill-rectangle
C-x r l		bookmark-bmenu-list
C-x r m		bookmark-set
C-x r n		number-to-register
C-x r o		open-rectangle
C-x r r		copy-rectangle-to-register
C-x r s		copy-to-register
C-x r t		string-rectangle
C-x r w		window-configuration-to-register
C-x r x		copy-to-register
C-x r y		yank-rectangle
C-x r C-SPC	point-to-register
C-x r M-w	copy-rectangle-as-kill
