The simplest way would be to just piggyback all pins of chip 2,
except /CE, onto chip 1, then lift chip 1 /CE from the mainboard and
have a switch for selecting either chip 1 /CE or chip 2 /CE to
connect to the mainboard, possibly with pull-up resistors on both
chips. (ideally only the one not selected)

Beware that TSOP packages demand very skilled soldering.
