That assumption holds only if your various other assumptions hold. My
opinion is that they probably don't. (BTW - I'm pretty sure, given that
every single asymmetric JCA crypto api takes a PublicKey or PrivateKey
you're going to need to mirror those classes at least; you'll also need
a ParameterSpec and a GenParameterSpec class with whatever underlying
supporting classes are required to deal with KeyFactory's)

There are virtually tons of third-party encryption libraries out there using a
PublicKey
as input argument but internally do things differently depending on if it is an
RSAKey or ECKey. This is also needed for JSON (JWK) serialization.
