The goal is to get to exactly what you describe, with drag and drop tools that then basically give you an export of all your interconnects and performance analyses. As you point out, the reality is that the devil is in the details. For now, Vesper is focused mostly on surfacing the high-level, sanity check interface concerns and performance calculations, but I hope it can still add value at the concept definition -> proposal -> PDR phase of a program.
I also agree wholeheartedly with your other comment that some of the biggest challenges are jumping through the regulatory hoops like FCC licensing and range safety, so maybe once I've got the technical stuff limping along I can take a look at how to incorporate that process somewhat.
