Can you look at other ways to group the toys based on how they are played with so there is less movement of toys such as animals with blocks.

Try to switch out the large carpet/toy area and make separate play areas there such as fisherprice playsets with little people in one area and on the other side of the divider the blocks and animals.

Watch for play patterns and decide if some of the centres such as playhouse are taking up too much space for the numbers of kids/amount of time spent there and adjust accordingly.

Double up use of some areas such as the quiet time to have books, puzzles, tabletop toys - things you play with all by yourself.
