Hi Gerald,
Yes, the four wheel can lose control if the steering wheel is in the air. The
4-pivot design would require 4 donor bikes, which is quite excessive for just
one person. Perhaps using small caster wheels as outriggers would be more
reasonable.
For the tadpole, in addition to the hub/differential challenge, I am not sure
how turning/seat rise would be, but it's worth a try. By the way, turning the
rear wheel may be a viable option, by hand or leaning...
