Let's try maths on that! An Imperial Star Destroyer is ~1600m long, and has a volume of ~9.3e7m³ [1]. At 1/4 scale, it would be 400m long and have a volume of 9.3e7/4³ ≈ 1.45e6m³. The largest zeppelin ever made was the Hindenburg, which was 245m long and had a volume of ~2e5m³ [2].
I think your dream is unlikely to come to fruition, but zillionaire is in the right ballpark!
