Different number of address bits, so nope.
It **Might** be possible to get clever with a 32M * 16 part, but it is not going to be pin compatible so you are looking at a board respin at the least, and some **Careful** reading of datasheets to check that you can make it work with only one byte lane in use.
The 8 bit parts are expensive because nearly nobody bothers with them these days.
