Okrand has never used or commented on using {'e'} with a copula pronoun (i.e. a pronoun used verbally to mean "to be"), so we don't know if {'e' 'oH} constructions are acceptable or not. If they are, though, your sentence is probably grammatically acceptable, though a little redundant. There is the question of whether {vIghro'mey} and other animals are actually capable of intention and can therefore use the {-ta'} suffix, though that's more of a philosophical question than a syntactic one.

(Although, since {'e'} is a pronoun, maybe it can be used as a copula too... perhaps {chabHommeylIj Sopta' vIghro'wIj 'e' vIt'e'}? Actually, no, that's too crazy even for me.)

The proposed version with ‘e’ might be technically correct, but I have a hard time believing Klingons use verb-acting pronouns in sentence-as-object constructions. The final verb in an SAO should generally be something simple and unexceptional.

This sounds more like a subjective stylistic choice rather than a grammatical rule. I agree that in most cases there's probably shorter or clearer ways to phrase a given sentence than {'e' 'oH}, but I wouldn't rule it out entirely just because most Klingons wouldn't phrase it like that.
