As far as I can tell, not without some hardware modification.
According to the schematics found here:
http://gnuradio.org/trac/browser/usrp-hw/trunk/usrp/interface.pdf?format=raw
The JTAG section of the FPGA is pulled either high or low and has no
other connections. You're obviously free to do what you want with
your hardware, but I don't think you'll get much extra support from
the mailing list?
I could be wrong, so please have at it!
