Cross-chargeability would be allowed if you got married before your spouse became an LPR, and you were a derivative for your spouse's GC process. But your spouse already had LPR status when marrying you, and would file a direct petition for you, so there is no primary/derivative relationship and you can't use cross-chargeability ... you are stuck with India as the country of chargeability.
When is your spouse eligible for citizenship? If/when your spouse becomes a US citizen, you don't need to worry about priority dates anymore.
