No way? There are a bunch of ways to tackle the shape- I can imagine one employing Sweep. Or Loft. Or Press Pull and a sphere.
Second, *ideally* it would be nice if the fillets flowed into one another.
What's stopping you? Just add a Fillet to the edge where they meet. Of course, if you want the corner rounded, the Edge that feeds into the corner will be rounded.

Thanks for the video. You selected the Edge repeatedly in your demonstration- it highlights in blue and a control arrow is attached to it; you'll then have to enter a value or manually modify the arrow position to produce a Fillet. The image I included above includes a Fillet applied to one of what I understand to be the subject Edges.
I think @M>oolWorks wants to maintain a sharp corner for the vertical edge and just blend the 2 fillets. I'm not sure what that would look like or is even possible, if you add a small 0.0001 rad to the vertical edge you can get this but you only get an option for a setback fillet.

Very nice, Mark; your results resemble what might be had with a Replace Face. I had to work the Fillet on both sides of the Body to get your results. Hey, what characterizes a "setback fillet", anyway? -what distinguishes it from a Rolling Ball?
Another way to tackle it without the slight edge rounding would be to select the second small Line segment from the top of the Fillet and apply a Variable Fillet- shown here going from zero to .029 at the top:
@mavigogun See attached file. You need to do all fillets in one feature to generate a setback fillet on corners with more than 2 fillets meeting.
The file has 3 components. One how to blend and keep a sharp vertical corner with equal fillet rads, just did this one as a practice. Second one used unequal rads, looks pretty ugly. last version is using a fillet set filleting all edges in one go.

@HughesTooling, Mark, as you illustrate, Fillet order can yield radically different results. Check out this image, in which the Edge of the Red Faces have been drawn across the concave Blue Fillet and over the Convex Green Fillet. Wild, huh?

@mavigogun Setback fillets have 2 uses I think. One to allow patching\filleting a corner where 3 or edges come together especially with different rads and second just for appearance.
There quite a good thread here on the Rhino forum discussing filleting edges on high quality consumer produces where simple G1 fillets are not good enough. Pascals' first couple of answers explain quite well. Here's another thread worth a look on multi blend corners.
