India already has about 50,000 Gurkhas and has done so since 1947 when the 10 Gurkha regiments of the British Indian Army were split between the British and Indian Armies. I very much doubt they would end up in the PLA.
AIUI individual Gurkhas were given the choice of Indian or British Army. British Gurkha officers were shocked and dismayed that the the Indian Army proved the overwhelmingly popular choice and there was a resulting manpower crisis in the 'British' Gurkha battalions. Hubris at work.
