This is crazy. Looks like he got further than any of us.
Anyway, I asked him to try the one I've uploaded here - however, if this will be something that works like a charm on one PC and crashes on another, it isn't really a good idea to try to get it working.
I know why I was getting the black screen. That's what happens with AA turned on. It really is such a relief to see it work - at least in some form - I still have to minimize-maximize to make it work, but at least it doesn't crash or freeze or any other thing that a program usually does when it wants to get on someone's nerves.
Now, the weird thing with bloom, is that it sort of 'over-effects' the UI, HUD, while only adding a very subtle but good-looking glow to the in-game view of the battle map, etc. Still it looks great with minimal_ui. If we can't work the problem out otherwise, we (I - I'm sure you all have enough work on your hands) can just make a darker version of the interface for those who would like to use ENB.
I didn't experience any change in FPS.
Now, I'll try to get the other things working. SSAO, DOF - the later could help hugely if not over-done, as it is in ETW (IMO).
Oh, and here:

The sky makes it feel like Medieval 2. Anyway, I'll make some more pics as I keep working on this.
I keep forgetting how EPIC environment can get in RSII. Here's a reminder. Bloom gives a bit more to fog.
Then the weather changes... and things go from epic - to downright scary. Truly, RS2 can control your emotions as very few games can...
EDIT: Uhh, sorry for the double post, could someone please merge it with the one above?
