Right now I would say no. It takes a lot of development and time invested into these case projects. The other thing is a case will greatly reduce the size of packs that will fit in the already tight trays that the 1/18th scale cars have. It's such a small percentage of the market when it comes to cased packs that it's very hard to justify the expense to make cases for them. In the future it may be possible but for now no.
