I guess, it will do great for 50-70 epis. 100 is too farfetched. Cop stories are, anyway, oversaturated.
Hotstar has too many good thrillers in the pipeline with a better star casts.
The things that work with soaps and not with ott is that you cannot drag just because an actor is sick or something mildly goes wrong. Even if they are doing typical serial stuff in Aashiqana, they need to keep the script crisp from day 1 to day 100. That's near impossible.
