I was musing about the Caproni, but think it would not be distinguishable as anything special. The Re.2007 would work as a recognizable jet fighter, though. I think.
I am using HBGs Me 262 (bit small), Kikka and P80, so I would want all the fighters to be in that size even if they are not to scale among themselves. Maybe a Gloster at 700 would do it for me.
