Quintessential D&D (Half-baked ideas), Part 2

So building off of my "Half-Baked Adventure" and my sorta-update here is a plan.

Here is what I have at the moment.

Basic:  B1 In Search of the Unknown
AD&D 1^st Ed: C2 Ghost Tower of Inverness
AD&D 2^nd Ed: RM4 House of Strahd. Total cheat I know, but I'd run it as if it were in Ravenloft.
D&D 3^rd Ed: Expedition to the Ruins of Greyhawk
D&D 4^th Ed: The updated Tomb of Horrors

So some remakes and updates.  But all with classic roots.
Now to buy a copy of Expedition to the Ruins of Greyhawk.
