It sounds like, to me, that I can do whatever I want. It looks like a totally open ended assignment. You give me no guidelines as to how you want this constructed, so I'll do what I'm interested in. I think we can build something pretty interesting.
Remember - I cannot really do the assignment for you. But what I'll do is give you a bunch of ideas to get you started. You can go from there.
Building a philosophy, of course, has to start with a specific tradition. There are no totally original approaches to philosophy.
I think we'd do well with the brilliant, but obscure, Russian metaphysican Semyon Frank (1877-1950). Born Jewish, he converted to Christianity once he flirted with Marxism. He taught at St. Petersburg University, but was exiled after the revolution.
We can develop something loosely based around his most basic idea: that of the "All Unity" is a very common theme in Russian philosophy in both the 19th and 20th century. It might remind you a little of Plotinus, the Stoics or even Spinoza.
Let's try to build something based on this.
