Just my random two cents.
Yes it IS entirely possible that the eyepiece and prism and what ever else in the optical train are optimized to work with that objective lens.
HOWEVER....there is IMO a very high probability that the objective will work fine by itself with some other random eyepieces not designed to work with that lens.
Think about it for a minute. You would WANT your lens to be designed to be as achromatic as possible in the first place because fixing things downstream optically so to speak would just be that much harder if it was not so.
Or in other words....you can certainly tweak things downstream for better performance....you why would you make a mess in the first place then tweak it later?
