Well, what do you know. Even a blind squirrel can find an acorn once in a while.
That one qualified expert already exists. Its called the Magisterium. Your snipe about the revision of the Catechism only applies to translations of it from the editio typica, the inerrant reference copy.
"BTW, what "original" sources did Jerome use to compile the Latin Vulgate?"
The guidance of the Holy Spirit, the support of his Pope, a first hand knowledge of the language contemporaneous with the writings, the availability of the sub-scriptural writings of the Doctors and Fathers of the Church, a scholars education, and the scrutiny of the Magisterium.

Wow, looks he really got you, OR..! The Magisterium is the “qualified expert”. And what is the Magisterium but an Expert Speculator with a Vatican t-shirt and Rome Decoder Ring?
My sense of honor prevents me from playing poker with the incapacitated.
Drink up!
