Yes, but that interface is still quite experimental and incomplete in it's current state, the whole task is not really finished.
I would like to have the dumpcap interface stable before doing any such things.
Some things still missing:
- support for tethereal (probably some additional things needed)
- get list of available network interfaces (I think this could be done with current dumpcap -D option or similar)
- get detailed information about a specific interface
- get information shown by Capture/Interfaces
I didn't thought deeply at least about the last point and it seems to be some more effort evolved in it.

I see the reasons and I think it would be very beneficial to do so.
So don't get me wrong, I like your idea (in fact I had the same), but it's just too early to do it right now, without having to change this interface several times and therefore the capturing tools, too.
I'll try to implement the next steps in a way that hopefully won't make the dumpcap interface too complicated ...
