Why not use a close wound wire coil. There is plenty of room. Built a mono
160m Clipperton L using a wire coil. Amp works great and there is less room
in there than the 220. Performance is great. 100 in 1500+ out.

Micrometals 2 mix, usually a stack of 2 T200-2's wrapped with Scotch 27
tape, then Teflon insulated #14 stranded or solid.
However starting from scratch will require about twice the inductance of
just adding 160 to the amp.
Use the Micrometals turns calculators to see if it fits. If not there are
wider choices.
