Hello Soykan

If your main purpose is to reduce the exe file size, I sugest you use a exe packer to pack the code of your exe.

Try getting one of the followings ..

UPX : http://upx.tsx.org/
WWPack32 : http://www.webmedia.pl/wwpack32
ASPack : http://www.entechtaiwan.com/aspack.htm
PKLITE 32 : http://www.pkware.com/
NeoLite : http://www.neoworx.com/
Petite : http://www.un4seen.com/petite/

Hope it helps ...

Tell me if it helps ..
