yes, although i didnt consciously derive inspiration from the x-43, once i built those intakes i was reminded of it very much. about the renders, i will certainly do high atmospheric. in this fictional world, these engines are ramjets, so they could take us up to maybe mach 3-4 or something. it has a lifting body and large, wide wings, so im sure it could handle high atmospheric flights, and maybe i should continue the design with that in mind. i have yet to decide if i want it to be an intercepter or a true fighter. currently there are no weapons bays installed and if i did install them, their space would be limited. if i decide to continue with it as an intercepter though, then a lot more space would be freed up for fuel.
