Of course they are
I try to never do anything half-arsed. And, words are my career.
About lucifer and venus: Before lucifer became the "devil" or satan, lucifer was equated with light. For example, the enzyme in fireflies that produced bioluminescent light is called luciferase. Venus and lucifer were basically associated with light... note that the planet Venus is extremely bright in the night sky when visible (particularly if you're in a rural, non-light polluted environment).
Also in judeo-christian belief, lucifer was an uber angel, perhaps one of the most powerful before he "fell" to vanity.
Wings are a somewhat traditional aspect of angels, at least dating back to the late Medieval period. My thought is that this is why Angel has wingscars on her back which later turned into wings in Ep. 26.
Note the demonic looking first appearance of Big Venus. Ever seen Fantasia... and the end vignette with Mussorgsky's Night on Bald Mountain? (If not, find a copy and watch... the entire film is worth just seeing that). For some reason those two equate in my mind. Speaking of Big Venus, notice too that in the inital appearance, the Megadeus was the all powerful destroyer, seemed to never need to do anything than fire its eye lasers. In the end, Big Venus was the end all be all, as it eradicated Paradigm City in a slightly different way.
This does bring up the question of what stomped Paradigm City flat 40 years before. The one version of Big-O (didn't it have a slightly different colorscheme?) with a dead Roger Smith was clearly cored by something other than a Leviathan class Megadeus (unless there's hidden weaponry). I don't recall ever seeing whether Big-O's torso armour could take a laser blast or not; it seemed to be quiet pathetic if exposed.
Here's a wild hypothesis on the story line: What if Angel really is the director, but she's attempting to relive an event instead of creating a new work? What if Angel was the pilot/dominus of a superweapon among Megadei, i.e. Big Venus who was personally responsible for toasting Roger, etc. and found herself unable to live with what she did after the campaign, so she spends her time living in a fantasy of what was? And, that the scene in the control room was nothing more than hallucinations?
Long ago, when I had more free time than I do now, when I'd go to communities, I'd visit their graveyards to get some history. I recall one gravestone in Syracuse, NY at the large graveyard just off the campus of Syracuse University, which marked the grave of a WWI machine gunner who had committed suicide about 7-8 years after the war. While I don't remember the exact words, it was something akin to: Now he can finally rest, and can finally stop seeing all those he killed. Post-Traumatic Stress is a powerful thing.
