Nope.  The IIGS has 24-bit addressing.  The IIe does not.

IIGS memory cards support the way the IIGS looks at memory, as
a linear memory space of 16MB (the IIGS splits this into 8MB of
RAM and 8MB of ROM space, so RAM cards are limited to
8MB).

The IIe, meanwhile, can support no more than 64k at a time.
That means the IIe has to use bank switching.

The IIe is a much more primitive computer than the IIGS.  In
fact, the IIGS has most of the IIe on a single chip, the Mega II,
and switches into an emulation mode to run 8-bit IIe software.
