those woven fiber bowls/pots you see at the home improvement centers- will they be okay for larger nepenthes? (miranda esp)

I believe I must re-pot several, and I'm wondering if the fiber planters would work. Also, do I separate the individual plants? (there appears to be two or three together in a six inch hanging basket).

I'm no stranger to re-potting stuff, it's just that all them dangling pitchers add to the confusion!

Any instructional tutorials online?
