[Slonopotam845]

Would it be too too far fetched to make the connection between Drona and Drona Pushpa?

I personally think it is far fetched, unless used as a poetic metaphor by the poet in question

That what I wonder. Someone must tell me, -- Is there any mention of the 'Drona pushpa' people in the Mahabharata - the original Sanskrit version! If there is, then we can be say, perhaps, that the Punaanooru Song refers to Mahabharata. Could you check please!
