It is not my imagination. It is DOD USA intelligence based guess for H-10 or H-18 variants and H-20 in the reports of 2019 as well as 2020. I just tried to see H-6 engines and technologies being used to test a flying wing design and suspected PRC would proceed on . They have done it before for J-10/J-16 and J-20. They can do it due to prevailing situation in SCS.Nope ... there's no chance to develop a flying wing variant of the H-6. Please refrain from such fan-boyish ideas and stay realistic.
"A super-cruise/ super-maneuver able version of H-6" is simply impossible and the idea alone is ridiculous.
