Right now, there's not much point in bringing a Research Limpet along to a thargoid fight(most notably on a xeno limpet controller), since they're completely unrelated to actually fighting the thargoid.
So, what if using a research limpet on a thargoid gave it a xeno scan at the same time?
That way it's useful, as it would allow you to use a Xeno Controller instead, and save you the utility slot otherwise used for the xeno scanner.
You'd still have a tradeoff, as the xeno controller doesn't repair as well, but it would be more of a fair trade rather than an outright downgrade.
