As Indigo is not a Turkish Airlines/Star Alliance partner, I think the answer is no. The reason is that you're on two different tickets, so from the perspective of Turkish, you're flying on Indigo, which has no relation to Turkish Airways (i.e, you're the same as a random passenger). The fact that you have Turkish Airways status has no impact, since you normally need to be travelling on Turkish Airways (or with one of its partners) for it to have any effect.
