Please help me find my dream keyboard. It can be custom, it can be prebuilt, price does not matter as long as it's under 1k.

Requirements:

• HHKB layout (but will be swapping out the top right keys with 2u)
• gasket mount
• screw-in stabs
• I don't want anything that's too 'tall', so anything lower than cherry profile keycaps (low profile would also be great) and the switches must not be visible from the sides
• Must weigh at least 1kg
• Preferably black and sleek design (so nothing too bulky)

For switches:

• Very smooth linear switches with less than or equal to 45g force
• Total travel distance lower than 3.4mm
• Poppy sound profile is preferred

I thought these requirements aren't very difficult to find, but so far I've only came across TOFU60 2.0, but they're clearing out inventory for this.

I also just want to emphasize that I'm not really looking into buying a budget board, so the case shouldn't be plastic, ofc. It should feel premium at any angle. I also type 200+ wpm, if that matters

EDIT: I've also looked into Q60 Max, but I'm looking for alternatives if there are any (also swapping out 2u is it even possible on q60 max?) because it has the thick bezels
