I gathered from your first post that you weren't lifting at full speed. But it seems like your doing either double cardio or cardio + weights every day of the week. Are you giving yourself any days of doing nothing?
You don't even need to transition into crossfit/circuit training. Just shorten your rest times and employ routines that involve supersets, trisets, drop sets, and gain sets. As long as you're working your heart rate you really don't need to deviate from your normal exercises that much.
Given what you've told us so far, I can't imagine you being able to cut calories much further without going into a serious deficit. You may be better off tapering down to about 2000 and altering your routing to elicit some fresh response.
