Even if you combine the code into a single flowgraph?  It's been a
very long time since I tried it, so maybe there are new firmware
changes I'm not aware of; but I know that I've gotten something like
the following working with the *_path files modified to use different
daughterboards and the passed usrp object:

class my_top_block(gr.top_block):
    def __init__(self, demodulator, rx_callback, options):
        gr.top_block.__init__(self)

       (SNIP: Set up the usrp here)

        self.rxpath = receive_path(self.usrp, demodulator,
rx_callback, options)
        self.connect(self.rxpath)

        self.txpath = transmit_path(self.usrp, demodulator, options)
        self.connect(self.txpath)
