Yeah, no. Unfortunately because the entrypoint is using a cubic ninja exploit, you don't have the permissions needed to http unless you ROP them (which I think it's not possible). The ROP code is inside the payload you are trying to download and the ROP code is also responsible of launching HBL.
In short terms, HBL won't load. Even if it did, HBL won't have http permissions.
But you could download the payload by hand in PC, rename it accordingly, put it into the SD root and then do your cubic ninja qr. The code will find the appropiate payload like if it was downloaded by the system and boot it like it should. HBL will launch. You still lack http permissions.
If the guys have worked on http permissions escalation during ROP, you could then use http in HBL. But when you are in HBL http should not matter anymore.
