Unfortunately, you do have a sizing problem.
If you wired your two 12V 10A secondaries in series, and then used one of your diode bridge rectifiers, you will get about 31 VDC at 5A, not 10 A. If you allowed the voltage to sag you might get 10 A, but the voltage would be around 16 Volts or so. The transformers will also get hot.
If you wired the same transformers in series, and then used a full wave rectifier you would get about 14.8 VDC at 10A.
Like everything else in life, there is no free lunch in electronics. If you could return the 12V 10A transformers and get one of the proper size, you would be better off. Either that or reduce your max voltage and/or current specs.
