Upgrade SP601 to LX45?

Can the SP601 board be upgraded to the LX45? 


The FAQ is ambiguous:


6. Can I upgrade to a larger or faster device?
   A: Yes, you can but to do so voids the Xilinx warranty and support for the board will not be
      provided. In general, the CS324 footprint allows upgrading the on-board FPGA to the
      LX25, but is not designed to support the LX45T.

Can you replace the LX16 with a LX45?  Yes.


However, the LX45-CS324 has 218 IO vs the LX16-CS324 with 232 IO.  The functionality of the modified board will be dependent on which 14 IOs are no longer connected on the board.
