AFAIK this is not possible. Each image (32b or 64b) has a ImageFormat
number. You can use the ckformat command to get this: E.g.
$ ckformat Squeak5.3alpha-18456-64bit.image
68021
$
The VM has to be matched to that number. You may open a 32b image with a
matching 32b VM on a 64b host if you use compatibility libraries.
The class ImageFormat in the latest images has more details.
