Yes, electrolytic caps can be used in AC circuits. If you connect the
negative terminal to the negative terminal of two electrolytic caps (or positive terminal to
the positive terminal) the two electrolytic capacitors can be used as an non-polarized
capacitor, but use at your own risk. Electrolytic capacitors can potentially explode if
they are connected with the wrong polarity. The above mentioned method is a way to make
a non-polarized capacitor from two polarized electrolytic capacitors as outlined in one of the
manufacturer's own technical data sheets. I have the document saved to my hard drive somewhere.

This is suitable only for 2 absolutely identical polar electrolytic capacitors.
Non-polar electrolytic capacitors are industrially produced, but they have slightly larger dimensions than conventional ones. They can be used with alternating voltage  under certain restrictions. The main limitations are caused with large losses and strong heating of such capacitors on alternating current:

CD60 Motor Start  electrolytic capacitor  - powerful starting capacitors can be used for a short time during the start of the electric motor.

Metallized polypropylene film capacitors - non-electrolytic capacitors of this type have been seen in the Turkish video Kapanadze.

Note the diodes must be fitted to the caps or the caps will get hot and you would only get half the caps value and check all constantly for overheating!

No, I think in this case C = C1 = C2.
This is not a serial connection. Capacitors work through diodes alternately at full capacity. It is better to use  Schottky diodes in TO-247 case on voltage not more as 20 or 30 volts, the have smallest losses.

The problem with this is while one cap would be the correct way on one half the cycle the other cap would be reverse BIASED AND WOULD GET HOT! not a good idea at all!
Surgh's circuit would be better as it has steering diodes.
