Welcome to InkscapeForum!
I've heard some people say that they use GIMP to produce the EPS. That is, an image drawn in Inkscape, and saved as Inkscape SVG, then opened in GIMP and saved as EPS. I don't know if that allows the effects to be converted or not. But GIMP is free and open source, and would be simple to try it. I would experiment myself, but don't have the proper software to view EPS files.
If any collaboration or cooperation between the 2 organizations/communities were to happen, I doubt if it would originate on the Adobe side. In fact, I would be surprised if Adobe (license) would allow it, even if work were only done from the Inkscape side.
However, I always like to remind folks that Inkscape is still young in its development. There still is yet to be a version 1.0. Maybe the EPS conversion will be able to handle the effects, before too long?
Edit
If it's CMYK color that you need, you could try this Inkscape extension:
