Yes, it is possible to make a sealed beam unit with replaceable bulbs!
Think of it as a sealed reflector unit. The reflector is sealed to 
the lens. At the apex of the reflector is a glass envelope fused to
the reflector but open in the back, such that a bulb can be inserted.
Postitioning guides insure correct orientation of the bulb.
In the Cibie' version the glass envelope is partially masked for beam
control.
Since no atmospheric air can get to the silvered surface of the
reflector this type qualifies for DOT approval as a sealed beam
unit. The Cibie' BOBI's go for about $40/pair.
