Would love to share some input but I would need to see some pics of what you're wanting to work with. I will say though, that another option aside from paint trays are those clear plastic storage containers you can find in the kitchen and home storage areas of your local supermart. Like Rubbermaid or something of that nature and you can get them in many shapes and sizes. Durable and light and work well with rivets or screws when it's time to attach things to them.
