What would be the point?
That's the real question. There isn't much point to it, back when the toaster was useful the main way people added effects like the animated transitions or overlaid text was to play a tape on one input with the toaster superimposing the effect on the live video and recording it out to another tape deck. We got away from that years ago when the work method was to just record everything right to the computer and apply the effect and save the resulting video back to the hard drive. Then you just shared the video with effects to whatever medium you wanted (burn a DVD, upload to web, etc.) The flyer helped shift to this paradigm but compared to today the flyer doesn't really compress video all that well compared to MPEG4. All this requires in the modern sense is a single video recording device and a lot of CPU power and HDD space. Very few video capture devices even perform hardware compression anymore since CPUs are so fast.
So if the question is can an FPGA be used as a video capture device and a hardware compression/decompression engine-sure it can, there are designs out there for FPGA MPEG4 compression. The the next problem is that you'd need someone to write drivers for all this and support it in one of the non linear editing packages, probably forget about the classic Toaster software being adapted to something so new.
