Interest check- Shadowrun 5e set in Hellblazer universe

How cool would that be?

Hellblazer as in john constantine?

i think you'd be better off using a system less setting specific, like GURPS or something else. whatever system you end up with, it sounds pretty awesome though, would you be using cybertech or not?

I've thought about it before, shadowrun is probably a bad system to use. Without the Metahumans, Cyberware, Future Tech, Hacking focus, you're left with a really clunky magic system. Your best best is probably nWoD with some suplements that don't make fullblown mages, like Second Sight. The Playtest for Pathfinder Occult Adventures is out there, that seems to be in the same genre but a different setting than 21st Century London.

That was my curiousity, why specifically shadowrun for it?

Another possibility could be the Savage Worlds rules with the ritual magic from their Horror Companion.

Or Monster of the Week?

one roll engine, with wild talents for power building. unless, as stated there was a reason SR was suggested. i'm quite curious about that.
