Memory module question

Had some extra space on a PCB board and slapped together this last minute memory board...
Will I have a hard time making it work with PropGCC?
The header on this VGA Graphics Shield board was designed for the FPS module (SQI flash chip) with 8 pins.
But, I've recently come to realize that for something like a text editor, some SRAM would help a lot...
That was the motivation for this simple module with SPI flash and SPI SRAM...
But, maybe I've made some strange pin choices... Without thinking too much about it, I connected the flash SI and sram SO together and the connected flash SO to sram SI. Any issues here?
pin_FCLK=4 'flash clock
pin_FCE= 5 'flash chip enable
pin_FIRO=6 'flash MOSI, sram MISO
pin_FORI=7 'flash MISO, sram MOSI
pin_RCLK=8 'sram clock
pin_RCE= 9 'sram chip enable
