I want to try the tiniest 1590LB boxes

Hello guys.
After some pedals in 1590A boxes:

I want to try the tiniest 1590LB boxes.
The one I'm going to buy will be this: https://www.musikding.de/BoxType-LB (51x51x32mm).
I have one of this boxes to build a simple project that includes 3.5mm jacks and a toggle switch, so I have enough room for it.

I don't need buffer or a "classic" booster. I want to put into this box a schematic with a sort of mid filter with boost.
But to fit into the box a 3PDT blue footswitch, two open frame jacks (even Lumberg type), DC jack (12mm mounting hole with external nut), two 9mm pots and a stripboard 21x26mm (with low profile caps) it's not so easy, and I afraid I can't find a right fit method.

I looked at some gutshots, but I need some tricks.

Thanks!
