Yes. Nowadays, you can configure busybox to build a shared library and
use this .so (see helptext of that option for the big fat warning that
this is an internal API which is exported for convenience and that it is
not and never will be a stable API).

See standalone in the archives.
There were already at least two ways proposed how that will be handled.
Landley made a bash-script which used libbb.h and linked against the
.so.
I bolted it into the Makesystem, so you could say
make coreutils/ls
and that produced a "standalone" ls which linked against libbusybox.so.
(unfortunately in that patch i also exported this facility into the
menuconfig system, which was not well received and really should have
been a separate patch).
