Insta, there seems to be a workaround to get HDR in custom maps already:

Gonna try it with my oooooold Bounce remake :/
On topic: Woot, looks good! I think this map is defently going into the map-pool on BFE, should be a blast :>
EDIT:
Oh snap! Didn't think of the materials in DoD:Source have a channel for HDR, while the HL2 ones only have RGBA :<
Guess this only works with DoD:Source-material so far...
