Compose with repeated dead key

Hi list-

I am looking for a way to make hitting a dead key twice send the corresponding character to the console.

For instance to insert a circumflex '^' I would just want to hit ^^ instead of the current ^SPACE sequence, which I am not used to after many years in a X.org environment. There repeating seems to be the default..

I am using the stock fr-bepo keymap (kbd 2.0.4) where the circumflex dead key allows to type characters like '^', 'ê', 'ô', etc, often used in the French language.

At first I tried to add the following rule:

compose '^' '^' to asciicircum

but this doesn't help. Is it because dead_circumflex is equivalent to the COMPOSE^ prefix, so repeating it would lead to a COMPOSE^COMPOSE^ sequence instead of the COMPOSE^^ expected to match the compose rule?
