No, I don’t think that’s possible.

Interactivity “before the fact” can only replace covenants when the possible futures can be enumerated in advance. That’s not the case for fraud proofs, except for very simple ones.

Note that Ark can’t avoid the unilateral exit costs, with or without covenants. As far as I understand, the protocols sketched in this post could also be used in Ark for the case where the operator stops responding.
