What's next for 40k?

I'd like to see a dogs of war/diasporex type codex and races. I haven't played since 4th or 5th gen, and I seem to remember there being some vague rules for them in 40k and there used to be a whole supplementary set of models and books for them in fantasy.

The lore is there, there's loads of mention of other human subfactions within the imperium and tons of xenos that aren't part of the main races.

I remember in the back of a forgeworld book there was a whole convoluted ruleset for creating your own vehicles. I think that would be an interesting thing to allow for count as troops or something along those lines.

Either way, I've always been interested in the mentions of mercenary groups and how versatile they could make an army if you were allowed to actually field them. I think it would also be a good way of balancing out the races. Being able to run an imperial guard army with some sharp shooters or specialized melee troops would be interesting. Or running a Space Marines army and drop a squad to add two big groups of what are essentially equivalent to imperial guardsmen. Or you could run a merc army with the equivalent of tau sharpshooters and some heavy, terminator like units.

You could bring back squats, introduce slann/old ones or c'tan as leaders who have subjugated large groups of soldiers for interesting purposes, make units for demiurg, various abhumans, galg, etc. I mean, check this list out and tell me you don't see so much potential for these minor races, who show up in lore but are otherwise never mentioned or seen. Hell even the races comprising the Tau empire are barely seen except for tau, kroot and vespid.

And as a final case: There are already existing rules for such things, or there have been in other generations. And they had done it a few generations ago with fantasy. And the fluff is largely already there, just contrive some reason why x race can work with y race without immediately killing each other, and there's no problem, or make it that some races can't hire certain other races.
