Often when the B-pillar is omitted, there needs to be additional structure/bracing to reinforce the body to reduce torsional flexing that can occur...typically that adds more weight.
As an example, the 2nd gen of my 'Benz went pillar-less (B pillar) and all models gained 300# in the process.
Granted, it looked nice and gained rear windows that rolled down, but every model gained a lot of weight in a 180" long car body over the previous design.
Not to mention crash standards. When the 08LC was going through design, we did the feasibility
study on having a true hard top. The added weight and cost of the sheet metal was a big factor in its self on top of the added window mechanism/electronics weight and costs. IIRC the panel would had to of been a Hydro formed panel out of high strength steel. People complain enough about how much the LC is a pig. Between crash standards and EPA/MPG requirements, many of you wouldn't believe the balancing act it takes to design a car anymore.
