Using argumentum ad verecundiam as a verb

Just no. It cannot. If for, whatever reason that seems good to you, you wish to use a technical term from Latin rhetoric, then by all means do so, but only after explaining what you mean in plain English.

There is a very small set of foreign language words or expressions that may be used in English without explanation or translation but even then you risk being regarded as pretentious. If you seek to introduce into written English terms that even highly educated native speakers would not understand, then you will fail to communicate. You might also arouse negative emotions that will actively obstruct any communication that you wish to make.
