In short: 30k yes, 40k no. SImply because Stellaris is build to be 4x strategy not a rts. Also ther is not nearly 30k mods in the existence at all. It would be a nice change to command legions of The Emperor of Mankind. Oh and Imperium wasn't as xenophobic back then so alliances with aliens can be a thing. Also there's awesome end game disaster: the Horus Heresy...
Also there's bunch of human civs at various levels of technological advancement (from medieval to space age) that you could encounter during the crusade and vassalise/reunite with empire with other less friendly means.
