It's possible without the WWE Network, but it's the easiest way to get footage based on your needs. There is a Youtube page based on WWE women wrestlers that rips from the network. Cannot remember the name, but believe eddyspeeding runs the channel. Torrents could be beneficial if you're familiar on how to use them. Xtremewrestlingtorrents is where I get my wrestling footage.
WWE actually post 90 minutes version shows (for Raw, SDL is the entire show since it's 90 minutes) on their Youtube channel, but it's for specific regions that cannot get the show. Using a VPN and connecting to the different region (like the Netherlands) could allow you to gain access to those shows. Believe they've been doing it since 2016.
You can also request it here, but no timetable on when it'll be complete. Not saying you'll wait months for it, but it won't be complete in a day's time.
