If you don't want to change the size, you have to use shorter types for some of the other members if you can afford the range reduction.

Try looking at unions.

kooth can you please explain in little details?. thanks

A union is a variable that may hold (at different times) object of differnt types and sizes. The compiler keeps trak of the size and alignment requirements. The programmer has to know the current type of data stored in a union, so that adds complexity that you may not want.

But even by using a union, you will still have to sacrifice some of the data like Athar said.
