I really like this idea.
Not only would it make the playing field slightly more even, it would drastically help newer players, who don't all have access to the forums, electrum and end up with semi-competent decks and as a result don't get that much cash from grinding.
I doubt it would make much, if any impact on the people who grind for score/money with the top ttw decks, but it would hopefully help newer players a little bit, since (no offence) they tend to use decks which lie between the generic 'rush/stall/control' categories.
