Yes...this will work as well. Actually you can just run some landscaping to the stone slabs that are on the "wall" side. I would sculpt that ground to the stairs. This should take up less room depending upon the length of the stone slabs. In the area of the steps, you should be ok with any aggregate. You do not have to excavate completely, the more aggregate the better, but you should be ok. From all the pics, your soil looks pretty solid which is good.
For sure...agreed just go with one type of rock. Quite frankly, whether it's 1/2, 3/4 or 1" aggregate nominal, it will not matter...just compact it really well and you will be good to go. As mentioned, your soil looks pretty solid as well which is a real advantage.
Well...I was going to start describing tying it in and realized I really can't describe it without the size or style of the stone and the measurements of the wall and stone steps. All that said, I typically will rough it in with a a few string lines to visualize it before I start building it. That way I will know exactly what my dimensions are going to look like and where my issues are potentially going to arise at.
It looks like that is correct and is your concern that the wall block has that step back feature to it? Other than that it looks really good in terms of maximizing the space and having a nice clean layout and flow.
It is really difficult to know exactly how much more you would have to excavate, but it should not be that much more at all. Again, I would suggest around the steps to go with a similar looking (probably exact looking) wall brick or block that does not step back, but is a straight stack. That doesn't mean the face of it won't have some dimension. The only other thing you can do is build the wall, inside is your compacted aggregate and allow the stone steps to overhang...the aggregate should provide more than enough support and you will get a nice look at each end.
