As others have said, apple vs. orange.
Both have their place. So while the argument has been on what PCIe can do vs USB, certainly USB has strengths for certain cases.
So.. the answer is "no", but iMHO, it's because one is an apple and the other is an orange.
If you think differently, go and get on of those high speed USB 3.0 docking solutions that do displaylink to handle multiple monitors over your USB 3.0... and when that fails (and eventually it will), you will have a better understanding for why this just doesn't work.

NAME
usb_dev_qlf_descr - USB device qualifier descriptor
SYNOPSIS
#include <sys/usb/usba.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
The device qualifier descriptor usb_dev_qlf_descr_t defines how fields of a high speed device's device descriptor would look if that device
is run at a different speed. If a high-speed device is running currently at full/high speed, fields of this descriptor reflect how device
descriptor fields would look if speed was changed to high/full. Please refer to section 9.6.2 of the USB 2.0 specification. The USB 2.0
specification is available at www.usb.org.
A device descriptor contains the following fields:
uint8_t bLength Size of this descriptor.
uint8_t bDescriptorType Set to USB_DESCR_TYPE_DEV_QLF.
uint16_t bcdUSB USB specification release
number in binary coded decimal.
uint8_t bDeviceClass Device class code.
(See usb_dev_descr(9s).)
uint8_t bDeviceSubClass Device subclass code.(See
USB 2.0 specification of
applicable device class for
information.)
uint8_t bDeviceProtocol Protocol code.(See
USB 2.0 specification of
applicable device class for
information.)
uint8_t bMaxPacketSize0 Maximum packet size of
endpoint 0.
uint8_t bNumConfigurations Number of available
configurations.
uint8_t bReserved Reserved.
