There are some airframes which were split this way [for the life of
me, I can't now think of any] but another thing which isn't maybe
the best would be the connection [for conventional engines anyway]
of the air intake for the air box etc. Also, for oil changes you can
just drop the bottom cowl w/ a split cowl this 'may' not be the
case. The 414 I fly has a full top cowl and a hinged/split bottom cowl.. this to might be an option?
Fwiw..

The top of the cowl are frequently used as the upper side of a cooling plenum on air cooled engines. A seam there might make it harder to prevent pressure loss. Esthetics might play a part, looking through the window shield no seam shows. I can't think of any structural or aerodynamic reason - not to say there might not be some, but I can't think of one.
