My own experience is that for immediate effect of changes in
/etc/default/keyboard, ctrl_alt_bksp needs you to type

# udevadm trigger --subsystem-match=input --action=change

but for the other options, like caps:none and all that gumph
in /usr/share/X11/xkb/rules/xorg.lst,

# setupcon [-k]

will do the trick. However, neither is necessary after a reboot.

I avoid having to copy those files by appending my changes to
/etc/console-setup/remap.inc and then running
dpkg-reconfigure keyboard-configuration.
But I'm not making major changes like you, just some modifications
to make the VCs behave like X, and eliminating the annoyance when
you catch your finger or thumb on Alt as you hit the space bar.

# Ctrl-arrow keys need to send the same codes as in X/xterm.
Control keycode 105 = F51
string F51 = "\033[1;5D"
Control keycode 106 = F52
string F52 = "\033[1;5C"
Control keycode 108 = F53
string F53 = "\033[1;5B"
Control keycode 103 = F54
string F54 = "\033[1;5A"

# Alt-space may as well produce a space rather than
# nul Meta_nul or Meta_space
alt keycode 57 = F41
string F41 = " "

Most of the other changes I make are actually additions to
the   Ctrl-X 8   mechanism in emacs, like  ^X 8 ~ q   for ♪
and so on, just the ones I need; and I don't usually need
those sorts of chars on the command line, only when editing.

Cheers,
David.
