Hi Sean,
neither two pair nor three pair will work reliably into 2ohms from +-55Vrails

3pr 15003/4 can drive 4ohm to 50degree phase angle from +-55V. This will allow most speakers to be driven safely IF you keep the Tc below 50degC requiring the heatsink to be kept below 40degC in the worst operating condition.
Your proposal is getting closer to being workable.

BUT you still have the problem of insufficient drive current upstream.

When are you going to take on board the suggestions?
