Instead of increasing the duration of your workouts, you might try increasing the intensity. Increasing the incline on the treadmill can really ramp up your workout (pun not intended)! In fact, I've read that most treadmills are set at a slight decline, so if you don't set an incline of at least 1.0, you're actually running downhill. For your powerwalk, is there a hill that you can incorporate? (If you walk on the treadmill, increase the incline for five to ten minutes of the walk). On the bike or the elliptical, you could increase the difficulty level.
Sprints are also good. Try to do one to three minutes at your top speed on the treadmill.
Also, consider adding some cardio to your weight lifting routine during the periods between sets when you would normally rest. My trainer often has me do short bursts of cardio in between sets and it really increases the intensity of my workout. Things that he has me do include jumping from a squat and/or lunge position, running fast raising my knees waist-high for 15 seconds, jumping from side to side, and moving side to side on a step (or on the half ball thingy) starting and ending in a squat position.
