FItech timing control disaster
It seems like you want the rotor contact on the "advance side" of the tower contact What seems to me is you want the rotor to overlap the contact by about 3/4 of it's width, that is, 1/4 or so of the rotor contact "hanging out" on the advance side of the tower.
I would, if I were you, "just plan" after you get it basically running, to hack up a cap and check rotor phasing. This is going to change with advance, so check the timing, and if it's where you expect at low RPM/ idle, the rotor should be "just coming to" the contact in normal rotation. As you speed it up and the timing changes, it should "sweep across" the tower contact.
I guess you know? this is not a problem with mechancal advance in a normal dist because the rotor and advance mechanism are connected mechanically--on the same shaft
This is also why, for some applications, like older V6's that you used to see huge wide rotor contacts........so as the vacuum advance changed, the rotor would be "in phase."
