Do you mean that you want to keep using the LCD witht he broken SD card adapter, and add a different SD card adapter at the same time?
I have a couple of LCD controllers that work with RAMPS, and include SD card adapters. I never felt a real need to add a second SD card adapter. In any event, there aren't many different RAMPS board configurations. There may be other work-alikes, such as the MKS boards, but so far as I know, these are all derivations on the RAMPS with similar pin-outs.
In any event, rather than replacing your RAMPS board, why not just replace the LCD controller with one that has a working SD card adapter?
