Is a Bilinear filter possible?

I mean something like the SLG, but that adds Bilinear filtering.

Scanlines are nice, but seriously, that mixed with Bilinear filtering would go SUCH a long way to make old games look good on newer TVs.

Are there any devices like that? If not, is it possible?

I think you're pretty much alone in your demand for that.

Different video processors have different looks. You might prefer a Faroudja unit with DCDi or a DVDO one with diagonal interpolation over a XRGB unit for that matter.
