I fear that there's a fighter bias in DCS. I would love a heavy bomber myself.
The idea of changing the balance of a battle by bombing supply lines and runways seems so much more appealing than dogfights. But it might never happen unless people make their voices heard. If we can have a complex, multi-seat ASM module like the Mi-8, I'm sure a bomber, at least a dual-seater like the SU-24 wouldn't be impossible.
