Hi,

No, you need new motherboard UNLESS you wish to try something like this (given your machine has Express card slot):

Please note: This may not work as you thought. - Been there, tried that.

Your best option to upgrade to usb 3.0 is a PCI Express Card 54, if your laptop has one. Many HP entertainment laptos came with a little remote that tuck in the left side of the laptop. That spot for the remote is a PCI Express Card 54 slot. This slot will work with PCI Express Card 54 and 34 cards, but you may want to by a stabilizer to help hold a 34 millimeter card. A PCI Express card 54 could give you a flush mount or almost flush mount with 2 usb 3.0 ports. I have also seen some Express Card 34 with 1 usb 3.0 port that will give you a flush mount.

As for the bad, some people complain that they have to use the external cable to get more power from a usb 2.0 port. This will depend if you have 1 or 2 ports in use and what you plug in the usb 3.0 ports. Others complain that it is not perfectly flush. Get over it. Also be aware that the drivers will come on a mini DVD if you have a slot load DVD drive. You may want to download the drivers from the manufacturer's website put on a DVD-R, USB 2.0 flash drive, Hard Drive, etc. The drivers from the manufacturer's website may also contain many bug fixes. Other complain these are thicker than stand cards or too thick to be removed frequently. Read the reviews before buying.

In short, no! The usb controller is part of the motherboard, and the connectors that show thru the outside are dependent on the controller. Changing the connector will not do anything useful. The daughter card on the opposite side of the laptop with usb ports (to my knowledge) does not have an independent usb controller. It connect to the motherboard and the mother boards' usb controller via a cable. Modern computers have the usb controller built into the chip set (the heart of the motherboard). The exception to this may be some desktop motherboards with a ridicules number of usb ports and usb headers (for front mount usb ports) that use additional usb controllers to control the extra ports.
