I think it would only be studied if someone (like for example you) would
do that study, that is compare it to current ffv1 and suggest it as an 
algorithm for a future version. Of course you would only do that if/when
you see that as making sense. For example when it is better than the
current code, supports lossless and arbitrary image sizes ...

What i wanted to say with my reply is more that suggestions to extend
ffv1 in ways that improve it would be welcome.

That would only make sense if that is either a very simple & natural extension
to existing code or if it adds significant value over other existing codecs.
