As discussed privately I have changed things a bit. Here's the current state of play. In the deployers, I create WeldKernelControllerContexts for the MC beans if they are part of a deployment that contains weld deployments. The WeldKernelControllerContext has a reference to the BeanManager which is then used for injection from Weld to MC beans. Only MC beans with the @WeldEnabled annotation are available for injection from MC to Weld (you can/should of course use qualifier annotations etc. in addition to this). I created a WeldEnabled annotation plugin to handle this annotation and add the beans to the McFromWeldRegistry. This means that @WeldEnabled MC beans that are not part of a deployment containing Weld beans are available for injection to Weld beans in later deployments.
