By asking the court to abate you are submitting to the jurisdiction unless you are talking about the antiquated "plea in abatement" which isn't used very much any more and isn't in the federal rules and so can't be used. It was really only used when they sued you in the wrong venue or the court lacked personal jurisdiction over the person of the defendant, such as when they were sued in the wrong state.
I don't think you're going to get anywhere with this argument.
However, you may want to look for an FTC report that was released in the last year in which they addressed the issues that were occurring with suits being brought against the wrong person, in the wrong court, after the statute of limitations
had run, with no service, etc. I didn't read the report, just articles on the report but I would think ti would be a valuable tool in these kinds of cases.
