:I would suggest keeping: 
 * P Cygni (well known variable star and class prototype); 
 * ρ Cas (naked eye yellow hypergiant); 
 * VY CMa (contender for largest known star); 
 * ε Ori (naked eye); 
 * ζ Pup ? (hottest naked eye star?); 
 * μ Cep (the Garnet Star); 
 * Plaskett's Star A? (once the most massive known star); 
 * θ1 Ori C? (Trapezium member).
