Before i start, can i point out that i will not be participating in this project due to overwork on Hostage Situation.. its just an idea for you guys.
Here's an idea!
Pair up in teams of two, one an HL1 mapper and 1 an HL2 mapper.
Each creates a simple, fun single player map, then they show each other their work and attempt to make each other's map in their preffered game...
E.G. Mr. X loves HL2 mapping and signs up for this idea with Mr. Y who loves HL1 mapping.
Mr X makes an HL2 map and gives it to mr Y who has made a HL1 map which he gives to mr X.
Then, Mr. X attempts to re-create Mr. Y's HL1 map in source and mister Y attempts to create Mr. X's Source map in HL1.
