It's ok in principle. In practice it will be difficult to find such placements for the inductors that the 100uH one will catch nothing, but the 500nH one catches. Enclosing the 100uH inductor into a metallic box helps, but the box must be large to prevent it reduce the inductance. Bringing the 500nH inductor far away with long wires changes the circuit totally due the inductance and capacitance of the wires.
BTW Me and surely many others are curious what you actually are going to do. Any data available?
Addendum due the comment of the questioner:
To make a coil to have a substantial inductance its turns should have a substantial free area for the magnetic field to go through every turn. You have flattened the needed way for the magnetic field to nearly nonexistent. That makes the inductance and also magnetic coupling extremely low when compared to what could be possible with the same amount of copper.
Have circular or square turns. The coil can still be flat.
In circuit boards sub 1uH coils often are spirals. That's not practical if you need 100uH.
An open ferrite core ( a bar, not a ring) reduces radically the needed size. Still today in AM radios the antennas are so called ferrite antennas. It is a coil where the wire is wrapped around a ferrite bar (round or nearly flat). It catches as effectively as a half-a door size air core coil. A long enough ferrite bar literally sucks the magnetic field into the coil.
