Not really. One of the advantages of vector displays is the fact that the drawn lines are razor sharp with zero aliasing. Another is the fact that the hardware has very fine control over the brightness, allowing for very bright or very dim lines to be drawn. The bright ones are brighter than could be replicated with raster CRT displays, and combined with slow-decay phosphors made for some beautiful "trail" effects. A pixelated display of any sort can only yield a rough approximation at best.
