Depends on whether they are DIP packages or SMD. If DIP, depends on whether they were socketed or not. If not, take them out, add some nice sockets, and then do what you want with the op amps.
In addition to chip rolling (just swapping one set of IC's for another) there's also some discrete op amps that will fit into a DIP package with enough clearance. :)
Fun stuff to do if your gear isn't htat expensive. If it is, I suggest new gear instead. :)
Best,
