I don't think there's any right or wrong here. I can agree with both sentiments: leave it as is, and re-use the fabrics to make something you like. It doesn't sound like taking the quilt apart and re-using the fabrics will destroy a quilt that is worth a ton of money and
must be left untouched. So I think you should do what will please you the most. Some people would be most pleased with the quilt exactly as it was created, whether it was their cup of tea or not. Others would dislike the quilt as is, refuse to use it, and it may end up at Goodwill, which would be a shame. You sound like you are in that category, and if so, enjoy recreating the quilt into one you like better with good memories built into it from the vintage fabrics you slept under.
