What are the available options?  If it is required to use a key binding 
that works both in GUI and TUI interfaces (as RMS mentioned), I fear it's 
an impossible problem.

Unless of course there is an agreement to remap one of the existing keys, 
for example C-z (also available on C-x C-z), C-o or C-t (which are perhaps 
less useful than a "repeat" command, and less useful than other commands 
(I at least never use them)).  But such an agreement is highly unlikely.

Without the requirement of compatibility with TUI interfaces, the 
available key bindings are the non-letters C-! C-# C-$ C-% C-^ C-& C-* C-( 
C-) C-= C-+ C-| C-; C-: C-' C-" C-, C-< C-. and C->.  Among them it seems 
to me that C-= is a reasonable choice.

Indeed, but the majority of Emacs users don't want a modal structure, 
otherwise they would not use Emacs ;-)  And a single-key "repeat" would 
give Emacs a minimal modal-like structure.
