If the transformers are rated for 1 amp and you only need 800mA then why bother wiring it for 2 amps and then having to mess with a doubler? Doublers are a cheap way to gain higher voltage from a transformer but are inferior to a straight rectifier unless you use very high value capacitors. The voltage regulation tends to be poor unless you use a fairly heavy bleeder current and that is just wasted heat and power. IMHO go with the secondaries in series and use a simple straight forward bridge rectifier.
