This brings to mind a video game, where you have "life energy" that is sapped when you are successfully attacked, and replenished when you pick up the right object in the game. Call it the "grace-o-meter". So, a mortal sin caused the grace-o-meter to fall instantly to 'zero'. But venial sins chip away at it. How many venial sins until one reaches the point where the grace-o-meter is at 'zero'?
For that matter, how can you know if something is truly a mortal vs. a venial sin? The definition in the universal catechism seems rather vague and subjective.
I could tell you, but than I'd have to kill ya. :-)
I honestly haven't studied this aspect much. Some of it does hint of theologians with too much time on their hands. And then consider that an attachment to a venial sin can be a mortal sin...
Bottom line is all sin is deadly, if not repented of. Some demand immediate attention because of the gravity, but none are to be neglected or taken for granted.

I guess it depends on what you mean by "mass producing" and "distributing" them. The Douay-Rheims Bible is older than the KJV, so it can not be said that the Church had a reluctance to publish accurate vernacular translations.
Now would the Catholic Church just print up a bunch of Bibles and send them out willy-nilly to everyone, without following through on the command of Christ to go out and teach? I don't think so. Where there are teachers there can be Bibles.
