If I am understanding you correctly, you want legs, and a toe kick behind the legs. To me that just sounds like it would look weird (ie - confusing)
I think you can't have it both ways: it is EITHER a piece of furniture (with legs), OR a built in (with a toe-kick).
Having some hybrid thing would look like you couldn't decide what it is.
If you are dead set on having legs, then go all the way and put legs on it and make it moveable so you can do what you should be able to do with furniture: move it.
So, what is it: furniture or a built in? Make a decision and go with it.
If I were doing it, I'd lose the legs and make it a true built in with a toe kick. And I'd leave it there if I were to ever sell the house and move.
Just my $0.02.
