That's not how it works though. Self-reliance is needed for the majority of the stuff for affordability and self-reliance. But your most advanced stuff is what wins you wars, regardless of whether it's indigenous or not.
Consider a ratio of 25-75, where 25 is cutting edge, 75 is your workhorse. So, regardless of whether the 25% is indigenous or not, if it's not capable of facing the enemy, then the remaining 75% is useless.
The criteria by rank for 25% is:
1. Capability
2. Affordability
3. Self-reliance
The criteria by rank for 75% is:
1. Affordability
2. Capability
3. Self-reliance
So self-reliance is the least important anyway. There's no point in having indigenous equipment if the first 2 criteria are not met in either category. For example, the T-90 meets all three criteria, whereas the Arjun doesn't meet affordability or self-reliance criteria.
Anyway, against Pakistan, self-reliance is largely irrelevant during war, it's a peacetime problem. The war won't last long enough for it to matter. And it's a peacetime problem, because, as a poor country, we can't afford imports in such large volumes in order to equip and maintain a very large army. But if your indigenous solution is more expensive than the import, then there's no point.
The main goal of self-reliance is affordability. Capability is a bonus. If you get both, only then can your entire military be indigenous.
