Well look at what we have now, heh.
I fail to see the absurdly over the top reaction you're apparently speaking out against here. The OP's question isn't interesting, it's yet another "we should remake ______" that you see all the time on forums, and almost always boils down to "it'll look better" - gee. And how exactly will the Horrigan fight be enriched by in FP and RT ? Not saying that's better in the isometric view, but first person doesn't do anything for it, unless it you mean makes gamers think "zomg awesome boss, epic win!" in which case it might as well be Generic FPS boss. As someone posted earlier, remaking the games does cheapen the originals, and it's not like the originals are lost to gamers today anyway.
First, the over-the-top reaction? I listed some quotes upthread, but there is also this feeling of the knee-jerk NO WAY! in most of those replies.
Anyways, thanks for providing another example:

Ta da, there is more to this discussion than "it'll look better" and you even pointed it out - FP and RT are different from TB/ISO. But, it's still "No way, we can't even discuss remaking FO1/FO2 because it'll obviously be a crappy product".
Anyways, about Horrigan - sure that could come out as Generic FPS Boss Fight or possibly even lamer (stand in this exact spot and he won't be able to hit you nonsense) - but even still, VATS would make it different from what's already been produced. Regardless, that does not have to come out as a lame FPS encounter - and wouldn't it be at least interesting as an intellectual exercised to figure out how it might be done well?
Also, I notice that you haven't said anything about the Uranium Mines. Wannamingo infested uranium mines. That could be absolutely amazing in an immersive RT/FP engine.
