I've thought about two
Fat Man and Little Boy
Little boy specs, same length as Mission MPF 3, but take the handles and thicken them to 1/4 inch, thicken blade to 1/4 at spine and keep full flat or v grind, do away with the recessed pocket clip and mount it flush to the surface of the handle with two small screws, make the spacer plate an integral part of one of the handle slabs plus keep the screw slots for added strength. Increase the height or depth of the knife to same or slightly more than that of the Mission MPF 1, make the size of the portion of the handle that bends for the lock a 1/8 of inch in thickness which is slightly thicker than current, and last but not least make the entire knife out of Beta C ti not just the blade but the whole honkin thing. Lastly straighten out the top/spine of the blade for a little more belly in the blade and lengthen just slightly the length of handle material between the cut for the lock and the top of the handle so there is a little more metal up there to make the weakest point of a folder just a little stronger.
Fatman specs, almost an exact copy of the Microtech Option II, except with 1/8 inch thick handles, and blade, full flat or v grind, make the lock line straight just like the Mission MPF series and again make the whole knife out of BETA C TI, handles, blades, screws,pins, everything. On this knife too just a little more length added to the distance between the top or end of the handle and where the cut for the lock starts, and while were at it for a little added overall protection.
That would be my two. Never happen but nice to dream.
