Now make one with 20usb-c

  That would be a lot of power if you supported PD on more than two of them

    Well, that would depend on how much power you're willing to pump through on PD. PD doesn't in and of itself mean the downstream facing port support the full 100W (20V/5A). You could conceivably add a PD billboard and pump out the minimum supported wattage, which I believe is 150mA @ 5V, so 0.75W? [edit] Looks like PD2.0/3.0 supports 100mA @ 5V minimum. [1] Now what you could do that would be really neat is have a set power budget for all your ports, say 250W, and allocate that power on a first-come first-served basis. Provide a minimum of 5W per port, and then the rest is allocated in accordance with the power delivery negotiation protocol. Say you plug in a laptop, it requests 85W, and you give it 85W. This leaves a power budget of roughly (250W - (minimum)(20*5 = 100W) - 85W = 65W).

  And have each port support a different set of capabilities.
