The West would need to be a lot more actively hostile to India before India would even consider shifting to being neutral from the West, let alone aligned with China against the West.
Western hostility to India is an inevitable outcome of the Ukraine war. Countries are being pushed to cut oil and gas imports to Russia,
while India gives $20 billion a year to the Russian military. Any country that buys military equipment from Russia is going to become isolated soon adn they will be VERY unhappy with India doing that going forwards.
India's military purchases from Russia over the past few years have been trending upwards as well. I think they will be forced to limit this and cut imports from Russia to a bare minimum.
At this point it's very difficult for India to severe the military ties it has to Russia. They have spend tens of billions of dollars on them. It would take 10-20 years to integrate western equivalents. Can they even afford it? What do they do with their carrier for example? Even if America offers like for like replacements for free, can India even afford the increased maintenance costs of that? Not to mention while they are swapping over Pakistan could just attack them.
The only option India has in my opinion is to make peace with China and be prepared to make some territorial concessions in return for an informal alliance between Russia, India and China. Knowing how delusional Indians are I don't think they will do this, and I think the most likely outcome is an India that has poor relations with both America and China.
