They should be able to start eating wet food. You can mix some wet food with the milk replacer or some water to make a gruel and see if they can eat that. I probably wouldn't leave the kmr out for more than a few hours.

    6 week old kittens can start transitioning to more solids. There is a KMR transition formula that you can begin this week. KMR should be refrigerated once opened and discarded after 72 hours. I would pick up and discard any uneaten product from the bowl within an hour or so. I hope this is helpful!
