There is an awful lot of truth to what you say. Actually, I'd think that Gonzalez has a paper trail far more evident than Roberts' was.
An a conservative scale of 1 - 10 with 10 being rabidly conservative, I'd give O'Connor about a 4 or 4+.
I give Gonzalez a 6.
I gave unknown Roberts only a 7.
Rehnquist was about an 8.
Therefore, Roberts/Gonzalez would be MORE conservative than was Rehnquist/O'Connor.
I would welcome Gonzalez. And it doesn't hurt that he's hispanic.
The confirmation hearings were quite instructive.
