If so, what is the likelihood that epson2 would work with this

None. The non-free interpreter is dlopen()ed by the epkowa backend and
it converts the regular ESC/I protocol to the device's native protocol,
insofar possible. Mind you, there are *several* such native protocols.
These native protocol are not even remotely close to the ESC/I protocol.
You'd be better of trying to find a backend that uses something close.
For a few of the interpreter using devices, the snapscan backend is a
good match. For others, I don't know. Maybe sane-find-scanner can be
of help to check whether it's something genesys-like, I don't know.
While porting those interpreters at part of my work duties, I have
tended not to look at the closed source more than absolutely needed to
get them to compile and "work". That was about a decade (or more) ago
so I don't have any recollection anyway beyond what found its way into
epkowa.desc :-P
Do we have any documentation regarding the ESC/I protocol?
Cheers,
