Didnt they say in one of the HH novels that the space marines were to be planetary governors or something when the Great Crusade was over? The space marine chapters that arent really the governing type could probably remain as a massively overpowered police force. Even if humanity was to conquer the galaxy and there were no human uprisings, you cant control all life on every planet. New sentient life might evolve again and then the space marines can blast them into tiny, bloody bits again.

If humanity were to conquer everything, they would probably start reducing recruitment for the space marine chapters. There will be chapters that refuse to start reducing their size, which is no problem if they happen to be a chapter that can adapt to the space marines becoming governators. If they are not, other space marine chapters will probably step up to be executioners (space wolves for example).

When the transition period ends, the execution chapters could remain in that role, to prevent uprisings (the imperium isnt going to be friendlier i'm guessing so people are going to revolt).

The end of the eternity of war is going to result in another war of epic proportions, space marine once again fighting space marine and all that. the imperium might very well fall should it ever manage to win.
