Mark Himsley has written a filter for that which unfortunately is currently
only available as an ffmbc patch (http://mdsh.com/wiki/jsp/Wiki?FFmbc+0.7
, look for "framerate converter") but it does exactly what you want, i.e.
frame blending and has decent results.
I think Mark mentioned once the intent to port it to ffmpeg but I am not
sure. If you're in a hurry, you can apply it to ffmbc and use that (I hope
I am allowed to say that here but I would of course favour this filter to
be ported to ffmpeg).
