I'll buy Divinity: Original Sin Enhanced Edition - Collector's Edition (12.99€), which includes: Two copies of Divinity: Original Sin – Enhanced Edition, Classic games Divine Divinity and Beyond Divinity, Design Documents, Art Pack and Soundtrack.
The second copy of D:OS goes in my inventory and I'll have to add you and send you the gift. I don't know if it will be added directly to your library or if it will add a Steam gift in your inventory that you can send/sell afterward at your discretion.
In theory you'll also get Divinity: Original Sin (Classic), which is the base game before the Enhanced Edition came, and the two old games Divine Divinity and Beyond Divinity, as stated in the description of the Steam Gift found online: https://imgur.com/rhs8TKQ. I am not 100% sure of that information though, and I'll let you know what says the Steam Gift I'll get once I buy the Collector's Edition.
About the Design Documents, Art Pack and Soundtrack, I have no idea if you'll get them too or not.
