This sounds good to me!

A slight variant would be to have the object model a polytope (or
possibly integer points thereof in case of MIP) rather than a linear
program. And then the operations on equations (putting them together,
...) become operations on polytopes, like intersection, cartesian
product, ...

This could possibly help give more conceptual names to the operations,
and/or bridge the link with other software for manipulating polytopes.

Best,
