Maybe you can grab one of the vias next to the 3V Pad? That would also give a nice return path for the signals. But I think another joint somewere nere to the SD slot would be needed for mechanical strength, when inserting a card.
EDIT: maybe you can also release the source in the end, so anyone who doesn't have all his wishes granted can change it himself, so you don't need to accommodate everything.
I also had trouble soldering to the other capacitor when I did the mod, so I get that it's difficult there. But the other vias I tried to get ground from also weren't that easy.
But I really appreciate your work on that PCB, which will make it a lot easier in any case.
