The fact that both vehicles are Geos does not have any bearing on the parts that are used. The 2 vehicles are as different as a Jeep and a Ford. Any attempt to put the motor and trans in anything except an Isuzu will require building everything between the motor and car from scratch. Lots of money unless you are a capable machinist and have the equipment available to you. All Geo Metro/ Suzuki Swift engines and transmissions will interchange between the different years with some work. The 95 will fit the 92 with some work. The information that would be useful for the swap is available on other metro websites. Do a search on Swift GT engine swap and you should get an idea of what is involved.
