I wonder if the kitchen would be something that ought to go. It's a big item that will take up a lot of space. It sounds like you have lots of other great open-ended things for the kids to play with and the big items can find a new home. Do the kids *need* a ride on horse? Or can these things go to dads house? lol At least maybe one of them can if that's an option. Also, look through the dress up clothes and see what is too small or ripped and donate/throw away so that can be scaled back (I am needing to do this myself).
Six months ago I actually went through the playroom and took 2/3rds of the toys in there and donated them. My kids didn't see me do this and have yet to ask for a toy I donated to this day. You might be surprised that if you did scale back at least half of their stuff, thay may not even notice. Frankly, I was quite surprised they didn't notice at least a few of the things and boy did it feel GOOD to downsize.
It may seem a daunting task but it sounds like you do have the desire, just don't know where to start.
