Seems like the best way to fix something that ED can't be bothered about, is to fix it yourself.
Go to the file <your drive>:\DCS World OpenBeta\Mods\aircraft\MosquitoFBMkVI\views.lua
Change the Chase View lines
Look back (F4) will actually look back now, but only until overwritten by the next update or repair. I suggest using OVGME or Open Mod Manager to avoid this.
You can adjust the values to move the viewpoint back a bit into the cockpit, but it becomes very cluttered with the aircraft structures.
