To maintain the original design regulation (technical term for resistance, relative to the load) you must use the transformer at half the rated current, and it will produce half the rated voltage - i.e. 1/4 the power. Vdery inefficient use of materials!
For electrical efficiency, the core losses are very small. Taking efficiency as the power consumed that is not converted to heat, it is slightly more efficient due to the reduction in core loss - but the combined core and copper losses at the design voltages and currents are small even at the original design point, usually 5% to 10% of the delivered power.
