Thats imo impossible as we are talking about two completely different ways of gameplay.
Why in the world would something as easy as this be impossible?
It's just skill checks. You give bonuses.
I'm as skeptical of D&D Next's ability to cover multiple playstyles as anyone, but this is trivial.
-O
I will point out just how trivial it is with an example that [MENTION=2518]Derren[/MENTION] should know well (based on the SR icon in his side pane): Shadowrun.
It has a skill system that goes from stat checks, to skills, to concentrations, to specializations; from incredibly broad to monofilament-narrow. All within the same skill system. And in that game, it
works (I've played/GMed a fair bit of SR in my day, from 1e to 3e).
However, the SR skill system has something that D&D's skill system does not, that gives it balance and allows it to work: the costs. It's far cheaper to buy skills the more specific they are. If the D&D skill system did that, I'd be much more likely not to hate it, but it doesn't.
I mean in 2e, the "better" NWPs cost more than 1 slot, which gave it some granularity, but this disappeared in 3.x, much to the detriment of the system.
