My approach to this problem is to leave the early bloomers alone (out 
in the garden) and bring potted plants of the late blooming ones into 
a greenhouse in early spring.  Depending on where you live, when you 
bring the plants into the greenhouse and how warm the greenhouse is, 
you should be able to get the late blooming ones to bloom at least 4-6 
weeks ahead of schedule.  I guess you could also bring them indoors 
and keep them in a sunny room.  

I've also had some Golden Tiara bloom early for me in the greenhouse 
that I used for some crosses and then without doing anything they 
rebloomed later in the summer.  You might try bring the early bloomer 
into a greenhouse, let them bloom very early and then see if they 
rebloom later when the late bloomers are flowering.
