It "sounds" ok to me, but I see what you mean about wanting a "to" in there to make "identify" an infinitive. Let me run this past you: the "to" from "try to do" also acts an implied "to" to make "identify" into an infinitive. I'm using as models phrases like, "to live and die in L.A.," and "to live hard and die young." In those, a single "to" is sufficient for two verbs.
Yes, I know, those last two examples have conjunctions between the verbs where your example has "is". I'm just trying to come up with some rationalization to make your sentence reasonable.
