Yes, you can do this.

1. add "ARCH=i386" to "make config" and similar commands, for example:

   cd linux-<version>
   cp .../where/ever/your/dotconfig/file/is/dotconfig .config
   make oldconfig ARCH=i386

2. Run make-kpkg with an i386 specific environment and flags, like:

   CONCURRENCY_LEVEL=3 DEB_HOST_ARCH=i386 make-kpkg \
    --cross-compile - --arch i386 --rootcmd fakeroot \
    --revision <REVISION_YOU_USE> --append-to-version <APPEND_YOU_USE> \
    --initrd kernel_image

   The important thing is to set DEB_HOST_ARCH=i386 in the environment
   of make-kpkg and add the flags "--cross-compile - --arch i386"
