Suggest re-design board with battery-clip/battery-holder/battery-retainer for CR2450 or CR2477 batteries instead of CR2032 batteries?

  • CR2477 is 24 x 7.7 mm in size and usually has about 1000 mAh of capacity on average.
  • CR2450 is 24 x 5.0 mm in size and usually has about 550 mAh of capacity on average.
  • CR2032 is only 20 x 3.2 mm (coin cell size) but only has 200 mAh average capacity.

Alternative universal solder pads supporting fitting battery-clips/battery-holders/battery-retainers for either CR2477, CR2450, or CR2032?

I think that it might be possible to find a cleverly designed battery-clip/battery-holder/battery-retainer for CR2477 that could even be able to hold either a CR2477 or a CR2450 or even two CR2032 batteries stacked on top of each other, or what do you think?

PS: I personally hate to replace batteries so really looking to get a large battery capacity and a long time between replacements.
