There are a few different ways to accomplish this since the last couple RetroArch and HSM Mega Bezel Reflection Shader releases. I won’t get into all of them right now though. I’ll give you the simplest method for now, then update the post to show you some more.
Install Duimon’s graphics.
Make sure you can load the background that you would like to use properly.
Then open the background preset in a text editor and change the reference line at the top of the file to point to the preset of mine you would like to use instead of what Duimon has currently.
If you need help with the correct paths you can let us know but I think Duimon has posted examples of how to do this so I’ll see if I can find them and add them to this post.
I’ve also seen videos on YouTube where people have done this as well so I’ll see if I can find and share them with you.
That’s method 1. Method 2 involves leaving the first reference line as it is but adding a second reference line to the other preset you would like to incorporate.
This second reference file needs to be renamed from .slangp to .params though.
It should be fairly simple to do this but I just haven’t gotten around to trying it yet.
Again, you can let me know if you need additional assistance.

You might also want to take a look at my @Soqueroeu-TV Backgrounds CyberLab Special Edition Presets in the MBZ__3__STANDARD_FULL_REFLECTIONS folder. They require @Soqueroeu-TV Backgrounds to be installed though. You can use most of them in conjunction with my Custom Blargg NTSC Video Filter presets or the ones in the Options of various Cores.
