Worried about common-law SOWP application from India

[aster0id]

My partner with whom I've been for 3+ years, and have been living with her for around 1.5 years, got admission into a reputed PhD program. We are planning to apply through the SDS route for her Study Permit. I want to accompany her on a SOWP as her common law partner, and I understand that I will have to submit a lot of documents to prove our relationship, which I am happy to do. However, I am worried that the India visa office might reject our application because virtually no one in India applies for a common-law work permit visa, and living together without marriage is very rare and sometimes frowned-upon here, especially by the older generation. How likely is it that the visa officers show prejudice against us and reject my SOWP application? Or worse, her SP application? And if so, do I have any recourse?
