Ok so he wants something unusual. How about getting a 4* kit and an extra wing kit and turn it into a bipe. Definitely unusal.
There are prop driven "jets" out there but for the life of me I cannot think of who makes any of them.
How about something like this. They are not kits but defintely unusual like lawn mowers, witches, indy cars etc...

A 4* bipe? That could certainly be entertaining.
It'd definitely be unique at our field.
As for the flyingthingz...eh...maybe some day.
