you will run into many problems.. f.e.

how do they travel, if you put w40k and sw into one universe, the sw ships will simply be chaos infested hulks as soon as they go into hyperspace (warp) as they have no gellar field.

next problem: sw imperium  and whatnot is much more divided, whereas the Imperium of mankind is united against all outer forces

problem 3. psykers  on the scale of the I o M vs "force users"

problem 4: IoM is simply geared towards war as far as production is concerned... SW is not

problem 5: size of army detachments... SW is outnumbered
