When it comes down to the grand scale of recruiting armies and sustaining conquest, it seems there are 2 alternative methods. First would be to merge and recruit locally, second, let ranks replenish. Now the first method seems to me to be superior due to lower costs (than waiting until you replenish, which is insanely lengthy process), allows you to recruit faster, you use local levies in your army which brings flavor, and retains experience of troops instead of those smelly 0 experience replenished replacements. And you can't even start replenish turn 1 in a new region because it is of foreign population. So is there any way anyone has made this strategy viable?
