A couple of WAGs.
1. Use PT-6 turbo prop to help take offs with max gross, hot day and
high altitude field.
2. Make normal 4 engine take off and at cruise altitude start PT-6
turbo prop and shut two engines down. This config would save a lot of
fuel and help bottom line.
3. New version of PT-6 and 747 airframe used as test bed. Qualify
another (bigger) engine for UAV use to carry heavier load.
4.Testing at high altitude for possible use on UAV .
The testbed idea sounds plausible. #2 is probably not likely due to
prop's inefficiency at high mach.
