What's A Synonym for "Thesaurus"?

​What if Emily Dickinson had relied on a thesaurus? 
​
What if she had established a Thesaurus Club?

Do you recognize the poem below by Dickinson
​(but changed with synonyms from a thesaurus?)

"Optimism" is the item with boas –
That roosts in the heart –
And belts the air without conversation –
And at no time concludes – outright –

And candy-coated – in the Chinook – is heeded –
And bruised must be the squall –
That could disconcert the elfin Fowl
That conserved for others thermal conditions –

I’ve caught it in the most arctic plot –
And on the weirdest Deep –
Hitherto – at no time – at its most extreme Boundary,
It petitioned a smidgen – of me.
