I agree with Scott that it will probably fail like that, but unlike Scott I have had success rooting rootless suckers at that point before, most fail though.
To do it the way I have had success with would be to cut the top down to a quarter inch above the second to bottom leaf, rip off half of both the bottom leaves and put something over it that lets light through to act as a humidity dome and put the whole thing up against the wall on the north side of a building.
We get about a 60% take on m111 cutting in most years. However this year this heat has really kill a lot of them off. So far I have got 6 of 8 G.969 cuttings well rooted now. But they were all 3/8 caliper so lots of energy stored in them is the reason???
Agreed with what @KS_razerback said, trim that top off and cut the remaining leaves in half. All those leaves are just transpiring away the moisture of the cutting.
