That depends on the primary/secondary arrangement. If it is tightly
coupled (say 0.6 or so) the clearances will be hopeless. You could
however get around that problem by giving the secondary (and
primary for mag type coupling) the usual 4:1 or so aspect ratio and
then for operation as a two coil, hoist the secondary up out of the
primary to get the coupling back to a 2 coil level. If the 2 coil topload
is big enough you could also eliminate having to retune the primary
when swapping from one system to the other.
