So the front of the deck is the back of the leg? Sorted, sketches coming up...

[EDIT]
Right, these are a fair bit rougher than I intended, but they should serve their purpose...
Right, this how the leg currently stands, with the outer 'sleeve' stopping where the arrow's pointing...

...and this here is how it translates in deck mode' leaving a whole chunk of thigh and crotch dangling out the bottom.

If you extend the 'sleeve' up (it's currently where the dotted line is), roughly to the top of the lower leg, at the front, back and outside...

... the outer case of the deck should come down a lot further, making it look more boxy. You could also then fit things like speaker details to the backs of the legs.

You could also add a little flap to the back of each leg, near the top. In deck mode, these could flip out to completely cover the thighs.

I can try and explain further if you're still not sure.
