Okay,
They seem like very different songs. The Van Halen one has a classic 70's-80's brassy arpeggio-type lead with some chords in between. I can play that kind of stuff on any keyboard. It makes no difference if its weighted or not.

Now, the other track by Whitesnake has very different type of sound (very digital in nature. ALmost D50 like). The only fast leads in that track were guitar leads. The synth stuff was pretty slow and straight forward.

I am now a bit confused as to what you meant by the notes blending together. Originally I thought that you were talking about B3 type organ leads. After that I thought that you meant brassy Van Halen OB-x type stuff. Having Heard the track by Whitesnake it appears that you could be talking about layering.

Wich brings me to my main point. WHatever I heard in the two songs that you've mentioned can be played on ES8 or S90 without a problem.

My main concern is that you have mentioned being used to playing K3, which has very light keys. I must warn you that the conversion from light to heavy weighted hammer action will take some getting used to.

The only thing that you will not be able to play on the weighted action keyboard of your choice is classic B3 organ leads. Swiping and sweeping up and down a weighted action board can hurt.
I use my DX7 as a controller when I do that.

FOr the type of music and sounds that you are after an S90 wil be ideal. THe PHantom will do nicely as well, but mostly with DIgital type synth stuff and acoustic samples. Unlike the Triton or MOtif it lacks an analog modeling engine so needed for accurate analog emulations.
That's why an S90 expanded with AN1x sounds like a good solution to this delema.

But hey, by the same token a Phantom X with somehthing like the Nord Lead, Novation's Nova or Korg MS2000 doesn't sound bad either.

I'm sure you'll make the right choice.
Good luck.

Regards,
