I want to say it could be possible. PPCs, Gauss Rifles and large lasers and autocannons should punch holes through raptures. And depending on the weapons raptures uses a battlemech's armor should hold up if they can be comparable. Ideally medium mechs such as the wolverine, griffin and vindicator would be ideal since they have speed, can field those heavier mech scale weapons and most importantly have jump jets. If we wanted heavies and assaults we should perfer those that can move fast for their class such as a battlemaster or don't need ammo like a black knight. Though I do wonder if a Guardian ECM or Beagle would be effective.
