Change theme during a rebuild

Hello everyone,

I’m facing a challenge with achieving the following task, and I’m reaching out for help. I’m not familiar with the process, so I’m hoping someone could provide a good example or guide on how to translate the following requirements into a nix snippet or into a default file.

Here’s what I’m aiming for:

  • Set the global theme to Breeze twilight
  • Apply the Breeze style to application style
  • Apply the Layan as the Plasma style
  • Apply the Breeze light color scheme
  • Apply the Layan windows decorations
  • Adjust the Fonts DPI to 96
  • Download and apply Eleven Dark as icons
  • Apply the Layan-border Cursors
  • Set the splash screen to Oxygen

Is this possible? Your assistance would be greatly appreciated.
