The reason, you aren't finding anything, is that nobody really attempts to install premiere or after effects anymore on Linux. The alternatives have cought up and they are available for Linux.
- DaVinci Resolve provides the complete package. Video editor and (node based) compositor in one. Even outside of the Linux world there is a lot of momentum behind this tool, as I probably don't have to tell you. Keep in mind, that the free version on Linux has some limitations, that the free versions on the other OS's don't have (missing h264 support for example)
- Left angle Autograph (https://www.left-angle.com/#page=95) is a young product, having seen its first release earlier this year. It's a direct competitor to After Effects. A timeline based VFX tool. Unfortunately fairly expensive as well.
Back to your question: making things work with wine has a significant drawback. Your system can break with every update. So you're not making it work just once but over and over again.
