LOL - teach me not to read every word of your post
Nice track BTW, I would tone down the distortion in some bits where its seems to be on everything.
Some comments apply though - just I think it started with a sine wave instead. Tons more resonance at times. Perhaps some metasonix gear and a sherman filterbank would get you there or a bunch of decent similar plugs.
Either way - no way in hell a virus is going to do that on its own.
About the NL3 - its a much brighter sounding synth - much cleaner high end, filter character is quite different and quite good for FM sounds. The huge downer for an NL3 is you will need some fx to go with it. For the kind of music you do... that might actually be a bonus - sounds like your going to need some very analog sounding mangling, so even if you had a virus - its fx aint going to get you close.
For these kind of sounds specifically, you might be *way* better off going for an Alesis Ion - which IMHO is one of the more analog sounding VAs in terms of its osc character and has the advantage of being very cheap and then spending the difference on signal processing. The downer with the Ion, while it has alot of filter options, I much prefer the Virus filters. And of course its synth engine is rather more basic.
Spend you money where you need it - if you need very good clean synth sounds - then Nord or Virus or Waldorf according to taste. If you just going to mangle them to hell, then something more basic but with good meaty raw oscilators and then focus your cash on processing maybe.
