nope... but keep in mind, the reason no one does it is because it's a full-time job.
First off simply running a fe once isn't enough. To be fair :
You have to create a scenario (like perhaps a arcade machine with no trackball and mouse running emulators a, b and c). and set up each fe for the scenario, not qutting until the setup is complete, or as complete as that fe will allow.
Not only that, but you have to do this over and over again. Trying out each fe all over again upon each major release.
A snap-shot in time of what each fe is capable of is no longer valid given the rapid development of fes. Only a dynamic, ever current comparison would be of any use to anyone.
Also if you give a bad review to a popular fe or a good review to an unpopular one, prepare for the hate mail. If I've learned anything from this site, it's that some people are afraid of or are offended by strong opinions. And if you give really "P.C." reviews then they'll be watered-down and won't help anyone decide.
Of course a more impartial, chart of features would be nicer, but I believe to explain many of these features and if they really do anything interesting would require reviews as well.
I am not trying do discourage you from doing this, I just want to make you aware of what is involved. It would take a really dedicated person to take on this project and if a less dedicated person did it, it wouldn't turn out well and wouldn't be of any use to anyone.
