Official Ruling
No, it can't interrupt it. Until the processing for the 1st interruption has resolved, only 1 activation is possible for each "when [...] would" effect. In your case, until the deletion of the 1st only [Sukamon] A is resolved, only 1 interruption is possible for each "when [...] would" effect, so because [Sukamon] A's effect has already interrupted, it can't interrupt again.
