I've managed to tweak and port the Xperia 1 ii Pro Cam over to Xperia 1. App launches, works fine unless you change lenses (only primary works), go to white balance and, click the shutter 
Sharing the apk with you guys. Let me know if any of you can make it usable.

SELF TWEAK GUIDE
Here's the guide:
1) download the original apk - https://www.apkmirror.com/apk/sony-m...-apk-download/
2) download APK Editor - https://betadown.com/android/app-editor-pro/
3) run APK Editor and open original apk and select 'Common edit'
4) change version code to 2236423 and change version number to 1.1.1.A.0.7
5) save and install newly created apk (open apk from a different file manager)
And it should work
I hope someone tweaks more and make it work as it should.
