Could I incorporate wireless RF current sensor into EmonPi system? What are some basic hardware and software modification should I make in order to achieve this?

Re: Wireless current sensors?
The emonTx is a wireless current sensor (and more), and will send data to the emonPi.
Or is that not the answer you were looking for? Your question is somewhat vague and I sense there is a something implied that I cannot guess.

@Robert:
Sorry for any ambiguity. The question was that could I use a custom wireless current probe to replace EmonTX altogether and transmit data directly back to EmonPi (hopefully with minimal change in hardware or sofware) ?
Re: Wireless current sensors?
Yes, the only limitation is the message format, and if you get that right, you need not touch the emonPi. You'd probably still need to use a RFM12B or RFM69CW radio module and the JeeLib library (though you could create the same message format without JeeLib - details of the format are on the JeeLabs website).
The emonTx is fully open-source, so you're free to copy as much or as little as you need.
Re: Wireless current sensors?
Another option is to use web sockets, either an arduino type board with a ethernet or wifi shield, a esp8266 or many of the other platforms currently out there with network capabilities.
Simply use a "EmonHubSocketInterfacer" to create a listening port to which any device can send a string of variables to in the form nodeid val1 val2 val3 ...etc to the url http://IP.ADD.OF.PI:PORT, "PORT" is user defined in emonhub.conf (and will also need to be allowed in the firewall)
