I'm not going to lie, starfox; your coming off pretty strong. With a couple notable exceptions people that play traditional game are a pretty conservative lot, and pretty elitist one at that. So most people are a bit leery of change here.
So this is what they see: an interestingly titled post by some unheard of board member. Out of curiosity/interest, they check it out. Right out the gates your responses start sounding fairly conceited, with sarcastic undertones and a dash of condescension in the mix. It might have been a joke, but opening up posts with comments like that sets a tone and precedent, particularly when you are not well known to the community. Continuing our story, they swallow their pride and continue to read and answer you before arriving at what Sigoroth would probably quote and insert with the line: this. The ships you are creating are not necessary.
The ships you are proposing are obviously massively powerful and huge in scope. Since there is no model for them they would require scratch building, and I can say from personal experience not everyone has the skill to scratch build a model twice or more the size of an imperial battleship. This automatically makes people less than interested about the ship. Second problem is, as AndrewChristlieb so kindly mentioned, ships of that scale and power are difficult to integrate into almost any game and thus require specific scenarios, further limiting their use. Lastly the rules representation of what you are describing does not require new rules, just some reintegration.
TL;DR You are just making a ramillies class starfort with a different look. Just take that thing and work from there, finish it off by pricing appropriately.
