After some thought, I came with a short term solution (for me) I Removed the R12/R13 and installed a '2x2 header' This allowed me to use 2 jumpers to select FLASH or SRAM or unplug and connect jumpers to the header for my use. Unfortunately the spacing of the resistors is just under 2.5mm so its tricky to bend and surface solder the header. Although I dislike movable jumpers as much as the next guy, this may be a good solution with minimal impact to the board layout.
Potentially to maximize flexibility and minimize build/test cost, layout with top traces shorting where r12/r13 are located but with the 4 through holes. Send the board with the 4 through holes and the user can cut the 'flash shorts' and install a 2x2 header and the jumpers.
