This made me think that possibly you could make a very compact tank 
assembly by simply stacking six individual toroids with maybe 1/4" 
between them. Since so little flux escapes from the cores, they could be 
almost right up against each other and the chassis (as long as they are 
insulated properly). You could also select the core material to be 
optimum for each band. Maybe the 10/12m one could be air-core.

It might even be possible to connect the low-impedance sides together 
and then it would need only one bandswitch pole to switch them, as in a 
conventional tank circuit.
