As a Green Bay Packer Shareholder, there's a lot wrong with your idea. As per the 2011 Offering Document[1]:
1) The limit isn't 5% per individual, 30% per family. It's 200 shares. Total.
2) Shares can only be transferred to immediate family, defined as "the spouse, children, mother, father, brothers, sisters, or any lineal descendant of a shareholder". An improper transfer will give the Corporation the right to purchase the shares at 2 .5 cents per share.
3) "As is the case with holders of Outstanding Shares, a purchaser of Common Stock in the Offering will not receive any
Packers merchandise, through the purchase of Common Stock. However, purchasers will play a key role in facilitating
the continued viability of a professional football team in Green Bay and will have the opportunity to have a voice in
the Corporation’s governance. In addition, shareholders will receive an invitation to the Corporation’s annual meeting
and have the opportunity to purchase exclusive shareholder merchandise."[1]
Or in the words of Tom from "Lock, Stock and Two Smoking Barrels", "You get a gold plated Rolls-Royce, as long as you pay for it."
So what do you get? A piece of paper. The right to vote. The ability to purchase specially branded merchandise. It's not even really a fan club.
