I've been looking for some wild plants myself for quite a while. It can however come with some problems such as parasites and pests. In fact its very likely. It can be done though. I'd quarantine them for a while and maybe look into a bleach dip for them.
Duckweed is a great plant although its probably the single most annoying plant I've ever kept, especially in a heavily fertilized fast growing tank. It's a great food for plant eating fish as its very nutritious and it absorbs a lot of nutrients out of the water.
