The House of Bombay was originally being King Victor giving his Hyderabad bastard, Thomas-Rajesh, his own Princely State at Bombay (which was under direct British Rule before, more or less). Said move has mixed reception back then, with most of the Indian population receiving well having autonomy and democracy, while the Muslims was repulsed by Prince Thomas-Rajesh being a Christian despite coming from Muslim mother.
Of course, the resulting Islamic Rebellion ended up cementing the Hindu-Christian alliance, and The House of Bombay gained prestige enough, that when Russia started pounding British Colonial Holdings at Asia, the Entire British Asian Colonies from Kashmir to Malaya declare their Independence (with Russian help through the backdoor) as "The Maharajdom of India" with Maharajah Stephen-Aditya as (what else) Emperor of the Biggest Polity on Earth.

Yeah, the Indian secession was received poorly by the Anglo-Hanover Branch of House Hanover, but it remains an interesting fact that The Indian Maharajah would actually inherit British and or Hanoverian Thrones if The London Hanover becoming extinct (in male lines for the Hanover, and in all lines for British Empire), simply because the fact that they were still Anglican Christians and thus, can't be skipped because King Victor fucking legitimized Thomas-Rajesh as a Prince. The risk then doubled because while European branches only have one wife each, The House of Bombay practice concubinage and add that with having Romanov Princess married twice into the line (that cemented their alliance with the Russians).
Without Thomas-Rajesh's existence, even if India ended up separating from British Empire, they would likely becoming a Republic or at least having Non-Blood-Related Monarch coming from the Princely stock, and thus the existence of House of Bombay won't threaten the London Hanover.
