I think Steffen would remap something else to them, rather than the reverse.

FWIW my vile/xvile at hand (9.8) accepts to remap BS to ^D for insert mode,
and it works (and when applied to normal characters it removes several at a
time, as expected and unwanted).

        :map! ^V^H ^V^D

NB: Maybe there's a way to write a user function to backspace smartly over
chars and indent + meta-insert-bindings setting + key binding a "meta-key"
to that function + xmodmap-ping BS to that metakey, but that way it would
also void BS for other apps and I don't see any other possibility :(
