Just wait for the one they ask for. Sucks but nothing you can do. If you do what you propose, it could delay things further as you'll have to wait for them to review it, issue an RFE, then respond to that, then wait for them to review again. Their case review time currently is very fast according to https://travel.state.gov/content/travel/en/us-visas/immigrate/nvc-timeframes.html but who knows what RFE review times are. I don't think it's worth the risk.
