Unfortunately XIP (eXecute In Place) on ext2 only works for
memory-backed block devices, which a USB flash device clearly isn't.

However, the OP could use XIP if his system has NOR flash. Some linux
architectures (ARM, for example) support XIP for the .text section of
the kernel itself. As for normal files, I know David Woodhouse has been
working on XIP for JFFS2, don't know if that's already merged.
