Your idea ten years later

Ten years ago, you came up with an idea so great that WWE not only stole it, but they actually gave you credit for it online!

I'm sure it's gotten much harder now, but maybe some masochists on your blog could pull it off:

The Ultimate Wrestlemania Card!

Select one match from each Wrestlemania to come up with the Ultimate Wrestlemania card, while constrained by the following limitations:

1. Each wrestler can be used no more than once.
2. Each title can be defended no more than once.

(Bonus points for having every title ever defended at Wrestlemania defended exactly once…so your Wrestlemania XIV match is Taka Michinoku defending the WWF Light Heavyweight Championship against Aguila by default)

So if you choose the Randy Savage vs Ricky Steamboat IC Title match for Wrestlemania III, then you cannot choose the Savage/Warrior match for Wrestlemania VII because Savage will have been used already, and you cannot choose the Shawn Michaels vs Razor Ramon match for Wrestlemania X because the IC title match will have been used already.

Can anyone pull it off now?

Yeah, Lou DiPietro was one of my moles in for a long time but he changed careers a while ago.  
I think it's nigh-impossible to pull off the deal now, unless you split it into 1-10 / 11-20 / 21-30 or something like that, though.  Math is just working too hard against you otherwise.
