Ludwig's WRAP-UP
In summary, "may presumably be" is a grammatically sound modal adverbial phrase used to express a tentative assertion based on a reasoned assumption. As indicated by Ludwig, this phrase is correct, though not the most common choice. Its usage is most prevalent in scientific and academic writing, where cautious and precise language is valued.
