Download Store Apps for WP8 / 8.1 - "Regenmesser" (Nils Laute)

Stated in
On Windows Phone 8.1? No more app store for you after December 16, says Microsoft | ZDNet

Windows Phone 8.1 devices will soon have no place to install or reinstall apps.

MS has cancelled the possibility to use the Store App on devices older than W10M, but is there a chance to work around this?

As long as a Windows 10 mobile is still able to access it, would it be possible to fake the device identiy to pretend a WP 8.1 OS and then get the appropriate app XAP-file for this older version?

Probably anyone knows a way, to retrieve a different version of a Store App just by using HTTP requests and access the URL for the XAP/ APPX files directly.

I own three Interop Unlocked Samsung ATIV S devices for each Windows mobile version 8/ 8.1 / 10.
And I want to install this app to my WP 8.x phones too:
https://www.microsoft.com/en-us/p/re...r/9wzdncrfjj3q

Unfortunately, the binaries on W10m are UWP, and therefore cannot be used.
Instead, the store signals, that it is compatible with WP8, so I guess, there must be a plain .NET version available for download.

Can anyone access it and hand out the binaries to me?
