The cheese is there for meltiness and texture, not overpowering cheese taste. Cheap american cheese slices melt perfectly for the job. Also ciabatta is totally the wrong bread for a burger, it's far too firm. Americans all use Martins Potato Rolls, the closest we can get here is those cheap Warburtons sandwich rolls. The key aspect of the burger is the beef (which should be predominately ground chuck, sometimes with other fattier cuts added for juiciness), everything else is just there to carry it.
Or you could make a b*st*rd cheese a la the Modernist Cuisine guys and have the best of both worlds:

Blue Cheese, Smoked Bacon, 1 Large Musroom (same size as burger if poss)
Smoked Cheese, Bacon, Onion Rings, BBQ Sauce
Salsa, Guacamole, Jalapenos
It would hold, provided you don't release your grip at any point.If you like eating those ingredients separately off a knife and fork then go ahead.. because there's no way that burger would hold! More does not equal better..
I like 1/2 pound burger with bacon,egg,sauasge,kebbab meat and cheese. A sprinke of salad and lashes of cocktail sause. All in pita bread, bun aswell but it can't take it all.

They say 80/20 beef to fat ratio is best
