Thank you very much! ❤️

Fantastic!
I know from your various postings you have been working on this for a while, it came together. So very well done.
Oh yeah, great playing on the song as well 😀.

Thanx for the answers...
Anyway, here is the result of my shooting:
 

You are actually getting pretty decent times. As @andrei89 mentions, testing recording times until shutdown is now a regular issue. Here is one test:

Your time is holding up well against the X-T4. 😊
You might be tempted to slap a frozen gel pack on the bottom or wrap one around the body to keep it cool, but be careful because it will bring a lot of condensation and the water drops are not a good thing.
Some third party manufacturers are building cooling cases based on using thermoelectric cooling (for go-pro stuff or smart phones, etc.), they may have something for dslr/mirrorless bodies as well or give you an idea that helps you build a diy case.
Fujifilm’s X-H2s is going to come with an optional fan, which will not help you, but does show they are working to make things better.

You can, it will work, but …. consider the age on the X-T10’s battery, the X-T30 II will drain it faster, the newer battery is built with larger capacity. Also, the newer battery has the middle terminals being used by the camera to regulate temperature. The ones on the older battery are not activated for that.
If cost is an issue, there are several third party sellers that have compatible batteries.
