Steamless, Half-lifeless, Mac NS?

7th.Wrath

So, I am running a mac and am wondering if NS could run by modding Nightfire. (<i><a href="http://en.wikipedia.org/wiki/James_Bond_007:_Nightfire" target="_blank">James Bond 007: Nightfire</a> runs on the Goldsource engine, the same as Half Life)</i> If I got a copy of Nightfire running on my mac, could I mod it to run NS? The installer file is an .exe, so I would require the actual files and instructions of where to install.
