I don't think something like this would be possible, and even comercially viable. First of all the source code of the games was lost, meaning that working on the game to make it even work on a modern console would be very hard and time consuming. The amount of money required to pull something like that off probably wouldn't get close to the return they would get from it. It is impossible to expect those games to do even better than modern CRPGs that come on consoles (Wasteland 3 for example), which already are quite a niche market.
But let's say it would be viable to make this kind of thing in the first place, how it would work? I ain't going to completely write off as "it simply wouldn't work", it probably can, but it would be an absolutely awful experience. Those games don't have too much going on UI wise but they have a lot of "clicking" and moving your mouse around all over the screen. I heard that Paradox (studio behind HOI, Victoria, Crusader Kings...) managed to port Crusader Kings 3 to consoles, but there is one key difference here, Paradox games require you to interact with a lot of menus from the UI itself, and this kind of thing can work or at least be converted to a more console friendly UI. Still it must be an horrific experience that requires a fucking masochist to play.
And at the end of the day a 3d conversion (a fps rpg like) would require them to stray away so much from the originals that too much would be lost along the way, in other words, to put the amount of work and money necessary to pull something like this off, they are way better off simply creating Fallout 5.
The only way I think a port like this can even remotely happen is if Microsoft "ask" either Obsidian , but more likely InExile to remake those games as a modern 3d Crpg, along the lines of the wasteland series. It would be by far the better option, nothing will be lost and it will likely leave literally everyone pleased.
