I assume you meant X and Y as wives and A and C as husbands.
Your solution doesn't seem to work in the following highlighted step:
1. A-X couple goes first to next bank.
2. X returns to C-Y at original bank
3. X and Y go to next bank.
4. Y returns to her husband.
5. C-Y go to final destination.
X cannot be in the company of C and Y without her husband's presence!
Also, would you please use H1, W1 and H2, W2 for the clarity?
