Taskbar hidden icons are tiny - can I embiggen them?

Hello,
The icons in the 'Show Hidden Icons' pop up of the taskbar are so tiny (and badly designed, but that's another issue) that they're almost indecipherable. Is there any way (other than scaling up the whole desktop/display) to enlarge them?

Here's how crazily small they are, with lots of empty space around each icon:


...in context of the whole screen (scaled to 50% to fit here):


It's as if the designers of Windows 10 were all working on 640x480 monitors; I'm hoping to get a 5K monitor soon - and those icons will be microscopic!

Thanks in advance for any help!
