I don't know what "ignored in the context of interpreting keystrokes"
means, nor what LISP-3 means.
The `remap' thingy operates at the level of `key-binding'. I.e. after
the command loop reads a key-sequence, it looks it up in the keymaps to
turn the key-sequence into a command, and then it looks this up in the
`remap' sub-keymap(s) to see if it got remapped.
So if you want to bind the original command to a key, you have to trick
the remapping by using another command name, e.g.:
(defalias 'new-name-for-old-command 'old-remapped-command)
(define-key MAP [KEYS] 'new-name-for-old-command)
since the remapping will apply to `old-remapped-command' but not to
`new-name-for-old-command'. There are other ways, of course, such as:
(define-key MAP [KEYS]
(lambda () (interactive) (call-interactively 'old-remapped-command)))
