I would however suspect that converting from DC to AC is not trivial.From the design of these locomotives, adding a transformer would do. The space for it is reserved, it had been filled with a dummy load.
But as RhB is planning the complete renewal of the electric traction gear, it is more logic to use these same components also for the two former MOB locomotives, which will reduce importantly the differences between the sub-series. (641-649, 650-652, 653-654)
MOB will strip the electric traction gear from the two the locomotives and keep it as spare parts. This will allow to keep 8001 and 8004 going without important renewal.
