This all sounds like a great idea, but I would suggest that rather than
attempt to be command-line compatible with the existing tool, you
clearly define a set of command line arguments and their corresponding
semantics that you *do* support, ensuring that it is an accurate and
correct subset of the behaviour of the original tool, and implement
that. Ensure this covers the behaviour that is relied upon by the things
that you are aware of already (e.g. calibre). Otherwise 90% of your
effort will be on re-implementing esoteric or awkward features or
behaviours that are not practically required.
