Haiku can mount regular files directly as raw partitions, and the boot
partition is mounted as /boot on a virtual rootfs anyway, though it
won't work for vmdk files which aren't a plain image of the
partition...

BeOS had an fmap driver which used block lists in the partition the
image was, passed from the bootloader, to access it directly (without
having to mount the containing filesystem). I started implementing a
similar driver in Haiku but never finished.

Something alike could be done, either as a vmdkloop driver publishing a
device directly or as a partition_module which the device manager uses
to then publish entries in /dev/disk/.
