I use a variety of fabrics all the time including batiks. If you like it go for it. Be sure to use a shout color catcher when you wash the quilt for the first time. this will take care of any bleeding. Some people posted ideas on how to make this type of quilt different then the original pattern you showed. You might want to research those before starting but if you like sewing together all little squares there is nothing wrong with that. I do second throwing out very poor quality fabric. You know the type you can see through.
