Without a magnetic pickup, there is no point in changing to electric guitar strings, except that lighter gauge strings would be easier to play.

If you can order strings in from stateside, I suggest {Warning: 3 MB catalog PDF file} >D'Addario< EJ10 (0.010" - 0.047") or EZ890 (0.009" - 0.045"). Such light strings will not sound as full and rich as heavier strings, but these bronze-wound strings will sound better on an acoustic guitar than nickel electric strings.

Lighter strings will not apply as much tension on the neck, so the truss rod will need to be loosened a bit. A small adjustment goes a long way, so go easy.
