I think it's tough.
For cotton textiles, to be worth it to bring in either, you would need the production of southern cotton to be more than in OTL advanced, while British/American cotton manufacturing techniques were retarded relative to India. That would make it worthwhile to bring in artisans to produce cotton goods. Historically I believe both kept pace and proto-industrialisation eclipsed Indian production in time.
And that's on the EIC side; it would also have to be worth it in wages for the Indian workers to take the big penalty of moving into a foreign, Christian dominated (even toleration was largely toleration of different Christian faiths), quite xenophobic society, without eroding the competitive any cost advantage of producing outside India.
For porcelain, I would think it's basically likewise; differences would be that there's probably a longer window of Chinese technological advantage, but there are other difficulties on the reverse - porcelain producers are probably even more likely to be prosperous artisans than textile producers so the incentives have to be higher, and on the other, I believe the Qing state was quite protective of porcelain as a state economic secret (and had it been otherwise, the knowledge would have transferred earlier and faster, without as many European experiments to try and duplicate the qualities).
Basically it seems like it would be hard to get a competitive industry in both cases.
Some of these problems might be assuaged if you had a radically different history where minorities in India and China who were already Christian were specialized in porcelain and textile, and had a good "incentive" to move. State persecution, aka something akin to a "Chinese/Indian Huguenots"?
