I'm also not entirely sure what kind of shape you're really hoping to end up with at the convergence side...

A regular fillet is going to eat up a whole lot of space from that lip area - you may be looking for something called a "variable radius fillet" where you can give different radius values at different spots along the edge rather than having the whole thing done as one single radius.

Moi does not currently have a variable radius fillet method in it, so that's another thing you'd want to go into ViaCAD to do as well.
