They've already offered India domestic production for the Su57 in the past, so yes.
Doesn't matter if the over all shape is poorly made.
Its stealth shaping is badly made
Its meant to be a dog fighter in the era of BVR.
Its internal weapons bays are so poorly made that they can't properly fit any decently sized missile.
It uses plasma stealth, which isn't a bad idea, but its used in a way that it wears out extremely quickly.
Its just a badly designed fighter.
For the FC31, when the Chinese realized that their initial prototype had a number of physical and internal issues, they had the common sense to go back to the drawing board and redesign it, thus we got the J-35A. The Russians refused to do so, despite being told repeated by their own experts that their own design was and is shit. They stuck with it. Making it flatter, or adding flat nozzles to it won't change anything dramatically.
