SRx1-PSU Distance to first pixel and uninsulated attic spaces

Hello! I'm building an installation that has 8 SRx1-PSU off of a F48v4. It is looking like I'll need to put 2 SRx1-PSU devices into enclosed, uninsulated attic spaces, meaning they can get very hot (well over 100ºF), plus the power dissipation from the power supply and the SRx1-PSU.

I would be able to move them to an interior spot that's 20 feet away and run a smurf tube through the attic space instead. I'm using 5V SK6812 RGBW pixels.

- Would I be fine with the longer run away from the controllers (20' @ 5V data)?
- If so, what wire gauge should I use?
- Would a reasonable backup plan be to splice some sacrificial pixels until it works, just pulling it repeatedly through the smurf tube?
- Is overheating in an attic space a concern as well?
