You could possibly contact Gopher (Dan) directly. He may make one for old-time sake. I'd go with the smaller one (think its the Merlin) The 16mm HDPE makes it a fairly chunky frame ( I find 10-12mm works fine at kestrel size ).
Flicks McS would be my go-to if you can get one of those. But you'd probably need to make it or have it done custom.
