Why, yes, it can. You can replace your 4 spoke with any 986 or 996 3 spoke wheel.
Even the tiptronic wheels will work on a manual transmission. I bought a tip wheel and while it looks a little funny, those thumb switches are going to be used for fore and aft rocket launchers to eliminate tailgaters and the lunatics who drive faster than me or beat me in races.

After you disconnect the battery as seen in photograph one, go drink a beer and smoke a good cuban cigar. The airbag can go off if the battery is not disconnected for at least 45 minutes.
Don't let this warning scare you off... this is a very easy job and fun to do. Took me all of 20 minutes outside the beer drinking and cigar smoking time.
