Two big cards in one panel, is it possible?

I have a display on the wall where I use Picture Elements in “Panel Mode” for a view of my place.
But now I also want the Home Feed card side-by-side so I can use some of the display to view new events.
But I don’t find any way to do this and still have a big Picture Elements card.
Does anyone know, ? or can I include the custom Home Feed Card inside the Picture Elements somehow?

This is the home-feed card:

Not panel mode:

Panel mode:

This is what I want: (made in Paint):

This looks like a job for custom css. You would need to use panel mode a horizontal card and then in the horizontal card set each of the two cards to a percentage width.
