Yes, but the problem is still the dispersion. With my setup the SA gives ~30A/pixel and the Spectra L200 gives 1.6A/pixel. This means the same light is spread out over a much greater area. Maybe using the L200 with a lower res grating like a 200l/mm rather than the 600l/mm that it comes with would be a reasonable compromise.
