Perhaps Blake, as (possibly) the fastest of the RWBY team, would be able to cut the strings attaching the blades to Penny's pack. If she could get past the blades, it'd be easy. Dodge an attack, cut a string, repeat. If Penny is controlling the blades through the strings, each cut string equals one less dancing blade. The charge-up before the laser finishing move may not be the only opening, just the most obvious and easiest to take advantage of.
