This Guardian article titled "William Wordsworth review – inspiration and smoking chimneys" has this passage:
It is 14 years since the publication of Lyrical Ballads. Wordsworth’s income from writing scarcely sustains his Grasmere household: sister Dorothy; sister-in-law Sara; wife Mary (who never appears) and their five children. Smoking chimneys and cold rooms are not merely inconveniences, they are dangers to health. Two of the children die.
In the boldfaced sentence, can inconveniences and dangers be replaced with their respective singular counterparts as follows?
Smoking chimneys and cold rooms are not merely an inconvenience, they are a danger to health.
If that's possible, which is more natural, the plural forms or the singular forms?
