Fortunately they will both run happily on the same system as they install into separate folders.
I saw a post the other day (on the site that begins with a D that I have been prohibited from posting on because I dared to be critical about some of their products) that wondered whether a translation layer would be possible so that DS 4+ scripts and plugins would run on 6. I think that's unlikely to be possible because of the internal changes. Maybe some enterprising tech billionaire could have an AI trained so that you could just ask it "Convert this script from DAZ Studio 4 to DAZ Studio 6" I don't know, maybe ChatGPT or something can already do that. :)
You have to separate scripts and plugins. For plugins, you would need to create a compatibility layer between libraries or have a compiler that can target both libraries and code that is compatible with both (or compilation directives allowing to modify depending on the target) - not impossible, but the libraries are not made by DAZ, they use existing libraries, so, most probably they do not the knowledge to do something so complex (license should not be a problem, if I remember well, those libraries for the interface, are actually "open").
Plus, it is in their vested interest to avoid that ;-), because in this way they force people to pay the premium subscription if they want to continue having some plugins that cannot be bought anymore.
For scripting, it would be simpler, and there are already examples, even at the level of programming language, even if not "on the fly", e.g. f2c. But again, simpler does not mean simple in absolute (it depends on various factors, included if the documentation about the scripting they have inside DAZ is good or not, and I doubt it), plus, just by chance there is new product on Daz, a "linter" for scripting for the moderate :-P ;-) list price of 99 USD (well, was discounted at 69 when I saw it, but still...).
