Is this a bearing wall?
It's a general rule (which is sometimes violated) that your load bearing walls are suppose to run perpendicular to your floor beams - so if you go under your house/level and see that the floor beams are running left/right - and your wall is running in the same direction, then it shouldn't be loadbearing (because the load would be put on just 1 or 2 beams - not distributed across all of them)
But Different types of housing construction put the load in some odd places - like my cantilever attic beams, for example - they are not overtop of any direct wall, instead, they distribute the load equally to all hallway walls with a web of beams.
You can play it safe, regardless - because i think a solution would allow you to deal with taking away the wall and still give yourself adequate support.
So - if your wall is 6' and your doorway is 30" or so - then you have 8/9' of wall to deal with.
Don't think of it like 'taking down a wall' - think of it like 'expanding a doorway'
Constructing it as a doorway gives you a header, king and cripple studs - and thus distributes any load to the outer points, the left corner and the right existing portion of the doorframe, while adding a nice look - and finishing off the entry and room smoothly.
I think you could do it - load bearing or not - and have it look quite nice when you're done.
At this present moment in time I am making cabinets for the kitchen - just in case you wanted to know what I'm doing when I'm not around.
