Thinking aloud and quickly, it seems almost as though you'd have to render a partial solution using one filter chain into a rendered image that would then be used as the sourceGraphic for the next filter chain. Inelegant at best, but I don't know of ways to put gradients or masks directly into filter chains - just feImage and feFlood - seems almost as though you'd need an feGradient (from which an feMask could then be derived using feColorMatrix together with the mythical feGradient)
Just a guess, but I'd love to be proven wrong.

Hello, Midway through a chain of primitives, I want to apply an alpha gradient so that the filtered element is completely visible at the left end and completely invisible at the right end. It can't be achieved with a mask because the SourceGraphic (which gets blended back in at the end) has to be fully visible; only the filtered version should have this alpha gradient. I'm fairly new to SVG filters. Having scoured the W3C spec, I can't find any way to achieve this. Does anyone have any advice? Thanks, Colin.
