Yes it can. Just call the exported interfaces for the blocks in question. On a related topic, I'll be adding an mblock-interoperable "message receive" method to GNU Radio blocks, so that you'll be able to thread-safely send and receive messages in GNU Radio code. The runtime system will ensure that the message receive code is only called when you're NOT in the work method.
