I suppose it depends on what one defines a god and a pantheon of such entities to actually be in practice, which of course is something quite personal to each person, and can vary a great deal depending on cultural upbringing or basic underlying assumptions about worldviews in general. In my own practice, for example, I treat the gods as beings that possess tremendous "integrity" you might say, because they represent something which truly is eternal and permanent, something which often cannot easily be named or represented in our limited imaginations. And so these archetypal beings can have many shapes or images that come to all point at them through the synchronicity that we call "gnosis", and how powerful that gnosis can be and how long it lasts, including how long it persists across generations and cultures and across history, is the measure of the "power" of these beings, and why they are often referred to as "gods" in the first place.
But, to your point, I do believe it is quite possible to "invent" such beings, if we are a bit open-minded about what we consider to really be happening when we "invent" a god. Perhaps "discover" could be another word to use that also works here and carries a somewhat similar energy to it. In either case, I do believe there are new "god-forms" you might call them, which are waiting to be discovered (or invented) by wise and clever people, such as yourself for example. I think the one you described in this thread is a very suitable example of this kind of generative process that can still go on even in modern times, just as it always did in ancient ones.
