Punctuation, including hyphenation, is a matter of style. Thus you should be guided by your manual of style. I use The Chicago Manual of Style, which gives a table of examples and rules to guide its proponents on hyphenating compound nouns and adjectives. Here you will find what to do with "word of relationship + noun" like brother officer (leave open) and "adverb other than the -ly type + participle or adjective" like often-minimalist (hyphenate before the noun it modifies).
Your novel compounds don't have a place in the table, so your own judgment must be the guide. It seems a good choice to me to hyphenate to emphasize the compound nature of the novelties, but that's just me.
