OK, here are some rough napkin calculations:
deltaV Ceres to L5: about 12 km/s
deltaE: about 6.7x10^28 J
Mass of Ceres: about 9.5x10^20 kg

Ceres is about 1/77 the mass of the moon, and about 1/6300 times the
mass of the earth. Something this massive at L5 would surely effect
the other libration orbits, as well as setting up further L-points.
My gut reaction is that it would turn L2 from a saddle shape into a
spheroid slightly trailing the present L2 point.
