On some of the connectors, the pins are pressed in from the 
card side.  So, if you unsoldered or unwrapped the pin side, 
you could, in theory, press the remains of the old contact 
out and press in a new contact pin.  i sold a box of 50 
unused Winchester double-wide DEC connectors on eBay some 
years ago.  No idea where they are now.
