I tried to google it, but I cannot to find any similar thoughts anywhere. I cannot believe that nobody newer wrote about it. I even tried to google in Japanese lol.
Stella Terrano's name is Sailor Moon coded, I'm sure about that. Usagi/Bunny name is word play, where her surname 月野 is literally translated like a "moon field", and her first name うさぎ is just a Bunny/Rabbit. But it is also homophonic, because it is similar in sound to 月のうさぎ, and this is just "Rabbit of the Moon", which is the reference to the Moon rabbit, an East Asian folklore figure. Sound の (no) is using in Japanese as a grammatical particle, functions as a possessive, similar to "'s" or "of".
Stella's first and second names are of Latin origin, where "Stella" means "star," and "Terra" in "Terrano" may refer to the Earth. If we use the same logic as above, then this could be テラーノステラ (ノ sounds identically の, it is just another writing system), Terra no Stella, and could mean "Star of the Earth". I think this is pretty poetic, especially considering she's an alien.
