The now out of production AG Russell DeerHunter was .06in thick FFG (4in blade), which sounds exactly like what you'd want. They do make the bird and trout and "hunters scalpel" versions with are the same, but with 3 1/8in and 2in or so blades.
Ben from Baryonxknifeco had some FFG moras in stock for a while, you might check there and see if he still stocks them. If not, I'm sure he can grind one down for you. Thats probably the cheapest/best option at this point.
