The Founding Fathers actually considered a proposal put forth by Madison that Judicial nominees would be confirmed by as little as 1/3 of the Legislature:

Mr. Madison, suggested that the Judges might be appointed by the Executives with the concurrence of 1/3 at least of the 2d. branch. This would unite the advantage of responsibility in the Executive with the security afforded in the 2d. branch agst. any incautious or corrupt nomination by the Executive.
