I'll try and stay on the question of the original topic.
The question that I have is what were each trying to acheive?
I think GM Pelligrini was trying to take an existing "-do" (Hapkido) and, in essence, revert it back to the "-yusul" (Hapkiyusul), from which the "-do" developed from.
I think his situation is different than Bruce Lee's.
I think Mr. Lee was trying to synthesize a new art from a variety of existing Arts.
Both may have used some of the same methods to acheive their goals, however, their goals were different.
Just my $0.02
So back to the original topic - this is a really good argument. Although, it depends what aspect of the comparison you are looking at. From the standpoint the arts that they created and what they set out to do, I agree, different goals.
But from public reaction and the "novelty" of what they did, I still think that it is a good comparison.
