Configure SPI on other digital pins?

The LED display problem is that I have two displays to plug into the board and only one set of SPI pins. I figured if necessary I can probably splice the appropriate data and clock wires for the two displays together and plug them together into their respective pins; or, since I have lots of empty pins, I was hoping another option would be to plug one display into pins 50-52 (the designated SPI pins) and tell the board that pins 24-26 (for example) are also SPI and plug the second board into them.

Would there be any problems with the operation of the board if I have two sets of pins acting as SPI?

Thanks for your reply.
