In reality, actually, Indian states around the Portuguese feitorias in India rapidly adapted European ship technology. As little as 14 years after Vasco de Gama reached India, Portuguese sailors reported seeing local ships using previously-unknown lateen sails. They became nearly universal in short order, as well as copying Portuguese shipbuilding techniques.
Kinda... sounds... a little bit like Westernising, don't it?
Addendum: Of course, there was no chance Paradox was going to leave the event such that Indian nations all Westernise, even though without Westernising Indian states are absurdly weaker in the 1500 and 1600s than they actually historically were (Portugal failed several times to try and take fortresses in India by military action).
And, of course, Indian states copying and adopting Portuguese sailing technology (at a time, incidentally, when most of EUROPE was still using square sails and otherwise not as advanced) isn't actually the same as Westernising, because the EUIV technology system does not allow for, say, Gujarat to adopt Western (really, Portuguese, since again, most European countries didn't have it) sailing technology but not, say, economic organisation and financial systems. No more than it can account for how Japan rapidly adopted the concept of European firearms and then surpassed the European countries they adopted the technology from (let alone how they later essentially dropped this technology). No more than how it can account for how various African empires benefitted through the triangle trade.
Hopefully eventually the entire tech system can be reworked from the ground up. In EU5, perhaps, if nothing else (though I'm not sure it's any more major than some of the systems already changed in the game, like colonisation).
