After a small mount of trial and error I was able to add fillet and chamfer capabilities to the SVG import modules. Now I can just check a box and tidy up the edges.
Here is the modified code:

Here is a before screenshot with square edges:
And after with a fillet applied:
and with a chamfer applied:
Each layer can have it turned off or on and since the minkowski() function adds some size to the objects the scaling can be adjusted to compensate for it:
I made the slider have several steps so the edge can be more customizable but probably isn't needed, I could also add a way to change the size of the sphere used with minkowski but it is also probably not necessary.
Of course there is still some work to be done to make this work where the two objects meet. I have an idea of how to implement it and I will be adding an update in a future post:
