Thanks,

This may not be what you are looking for but it is a
clever way to make a Hartley oscillator using two
inductors without any coupling between them:

"Hartley oscillator requires no coupled inductors,"
by Jim McLucas, EDN Design Ideas, issue of
26 October 2006. The example is an 18 MHz
oscillator using dual-gate CMOS FETS but the
principle of transforming coupled inductors to
two individual inductors would be sound for any
active device.
