Simple answer: No and No.
Although it may not be impossible to patch one USB network chip in place of another it is difficult and requires considerable expertise in circuit modification, network drivers, PCB layout etc. Just removing such a chip without destroying the PCB takes skill and specialist equipment.
It is far,far,far easier to connect a USB WiFi device to USB or an Ethernet-WiFi bridge (e.g. a TPLink) to the RJ45.
