Technically, they all approach the topic in different ways - so I would not replace any - may be rotate them - use the Puja set one week and the other audios the next week?
If I really had to pick, I would still keep the mindset audios in the stack - and replace the Wealth Stack 2 with Ashta Lakshmi Mahayagna + Navagraha Homam. The booted Bhoots might replace exorcism in some cases, but again, I would really alternate the Puja stacks with these.
