Tom,
    Unfortunately, the charge in each cap in series is equal. Since the 
Charge, Q = CV,  you would have C1*V1 = C2*V2 =C3*V3.   You can see that if 
C1 is .05uF and C2 and C3 both are 2uF(the small one rounded up to ease the 
math), the voltage across C1 would be 40 times that of the C2 and C3.
