Edited to add:
Shaya, I was thinking about this and maybe there is indeed a way to be lenient be-di'avad as you intuitively suggest. I don't know if this stands up to scrutiny and I would have to look at the sources again, but maybe:
The Ta'z and others are machmir be-di'avad with bishul. That's true. However, what if the Ta'z (and others) is speaking of a case of mamish cooking the meat and fish together, like in the same pot? In such a case, yes, chamira sakanta me-issura, and both would be forbidden even be-di'avad, even if let's say it's batel be-shishim or whatever. However, would that be the case were both to be cooked together in the same oven but in separate pots, where it's "only" the steam in the confined area that connects the two dishes? I don't know, but I'm not sure it's a slam dunk. I have to go back and look at it again from this different perspective. Maybe the key is the Sha'ch.
But maybe that's why the torah.org site said you need to ask a rav - since maybe therefore there can be room for leniency depending on the particular circumstances, such as the size of the oven or whether the fish or meat are liquidy.
But I don't really know, it's just an idea, something I have to think about.
Again, as always, ask one's local orthodox rabbi and don't rely on the rantings that I derive from general ignorance and stalk-trolling internet fora.
Shaya, I spoke with my local orthodox rabbi this morning and we went over the Sha'ch briefly. Here is the Sha'ch:
ז"ל ד"מ באו"ה כלל ל"ט כתב דלכתחלה אסור לצלות בשר עם דגים משום ריחא מילתא אבל בדיעבד שרי דלא הוי סכנה רק דרך בישול ואם הם סמוכים שהשומן זב מאחד לחבירו אסורים ואף דיעבד כדאיתא פכ"צ עכ"ל ומהרש"ל באו"ש סימן ל"ה ובספרו פג"ה סי' ט"ו כתב דמותר לצלות דגים עם בשר בתנור אחד אפילו לכתחלה ואין בו משום ריחא מילתא לענין סכנה דדוקא כשצולין אותן מחוברים זה אצל זה אסור וע"ש ובספר באר שבע דף ק"א האריך בזה וחלק עליו ופסק דאפילו בדיעבד אסורים משום ריחא מילתא אפי' נצלו נפרדים זה מזה בתנור אחד כתב דאפילו במקום דנוהגים להתיר לענין איסור בדיעבד ריחא מילתא ולאסור לכתחלה כדלעיל בסימן ק"ח לענין סכנתא אסור אפי' דיעבד וע"ש:
What I understood the rav to say is that the issue here is the mingling of the steam, not that the foods are being cooked together in the same pot. What I understood the rav to say is that basically the Sha'ch is citing two opinions, the first that even le-chatchilah there's room to be lenient, and the second that even be-di'avad it's forbidden. What I understood the rav to say was that le-ma'aseh "we" are noheg that le-chatchilah we don't cook meat and fish at the same time uncovered in the oven because of steam issues like the second opinion in the Sha'ch, but be-di'avad there is room to be lenient like the first opinion in the Sha'ch.
Also, here is the Darchei Teshuvah:

since the Darchei Teshuvah is seemingly citing authorities who may rule leniently in cases where the oven is big or the fish and meat aren't too liquidy, in opposition to the apparent ruling of the more stringent second opinion in the Sha'ch. In other words, even if one holds like the second and more stringent opinion in the Sha'ch that even be-dia'avad the fish and meat are assur, there can possibly be room for leniency depending on the particular circumstances.
