A longer wavetable will reduce interpolation noise, but it will not reduce aliasing. Essentially, aliasing arises when you skip through the wavetable too fast, so increasing the length doesn't help.
I am not sure the phasor~ arrangement I had in the first patch I posted behaves as you suggest when the frequency changes (unless I misunderstand what you're saying). I've attached a patch that randomly changes the frequency of a phasor~ and the saw~ that is acting as its sync-trigger. If you record a bit of this and examine the points the frequency changes (I just zoomed in using Audacity), there are no discontinuities in the waveform. You get discontinuities in the slope of the waveform (as in the attached image), but you never get the phase of the waveform being abruptly reset to 0.
Unless, I'm missing something…?
