Should work once you add code to read non-R package description files
to create a DAG. If you add such code, I will add it to the package.

Yes. Here's what the man page for makeDepGraph says about its
keep.builtin: logical value indicating whether or not packages that
come with a default R installation should be included in the
nodes of the dependency graph. The default, 'FALSE', is to
remove these packages from the return result.
A few other notes on using pkgDepTools:
* You will get much better performance if you set dosize=FALSE.
When TRUE, the code uses RCurl to fetch the HTTP header of each
package it encounters to estimate download size. This is slow.
* When calling getInstallOrder, you will probably want to set
needed.only=FALSE so that you get a complete list and ignore
whatever packages you happen to have installed at the time.
PS: I think it is smart to target BioC 2.0 since it is going to take
some time to refine your process. If you started with 1.9, then by
the time you had everything in place, it would be time to switch to
