The word 'cost' as an adverb?

[Ferdie11]

Hi,

Is the word 'cost' used correcly in the sentence below?


All of these, solutions can easily cost justify themselves in standalone implementations.



Many thanks.

All of these, solutions can easily cost justify themselves in standalone implementations.
First, I find the comma breaks up the text in a not-very-helpful way, and should not be in the sentence.
Second, cost justify is used as a compound word in a sense: cost-justify, so rather than cost being an adverb, it is part of a more complex verb.

All of these solutions can easily cost-justify themselves in standalone implementations.
