I already tried the theory of keeping this topic on track, see my post up top, didn't work all that well. But as long as were not talking about Bugs bunny or my cousin made out with my Valkyrie or something, were doin good!!
I have the 1/5000 scale SDF-1, I love it, but would rather have a 1/3000 scale, bigger is better with that one!!
As for matching scales, accuracy like theres no tomorrow. A great theory. But in some cases, why not just do all the Macross class ships, one size, BIG and loaded with details. No sense having having some 7 inch wonder of toy so you can have its counter part at 15 inches tall at 4x the price. But I guess that just an old school way of thinking.....I don't know.
But your idea of Model kits is a good one, that might be on the drawing board with Bandai as well since their model team scored big time with the VF-25 kits.
