I might point out that bringing the edges into final alignment might most easily be accomplished with coaxial lines trimmed to the right lengths. At most the line for 10 MHz would need to be ~66 feet long (assuming the usual 66% VF for polyethylene dielectric), and the worst case length for the 100 MHz signal would be under ~7 feet.
I suspect that the logic circuitry (and possibly the delay lines) for this project may need some degree of temperature stabilization as well, in order to maintain the desired alignment accuracy over time.
