Wic depends on too many things that are not present on target image.
pseudo and bitbake are two hardest cases. Making wic less dependent on
them would end up in much more complex code than wic has currently.

However, 'wic write [--expand]' functionality can be copied to simple script
relatively easy as it only depends on bunch of tools like parted, sfdisk,
resize2fs etc. I'd suggest to keep this functionality in wic as it's
handy to use wic to flash target media. This would create a bit of
overlap in functionality but it worth it from my point of view.
