Yes!

Just pay attention to your body and make sure it doesn't give you the wrong kind of pain. That's always the first and foremost thing that should drive your training. Some people don't have the core strength and stability to jump right into that, or they have old injuries (like me)... but I know you've been doing some form of resistance training for a while now, and you do move a lot in general, hence my recommendation of giving that a try.
The body responds to things that are new. If you want the fastest, most efficient response, you need an unfamiliar stimulus. I've seen compelling evidence that switching your rep ranges and your intensity after about a 5 to 7 weeks of training in another range does a lot to build muscle. High rep ranges DO have value, but not when they're so high that you're essentially doing a cardio session.
Cardio is good for your heart. But it does jack if you want bulging biceps, because the signal it sends to your body is to strip off as much mass as possible where it can and increase endurance. If pure cardio endurance is your goal, then sure---go ahead and make that your primary form of training, but if you want sustainable fat loss, or a healthy range of functional mobility, then some form of strength training should be incorporated.
