You can use an adapter to plug the 30A source into the 50A inlet box without any issues. The 50A inlet breaker is sized to protect the wires in the house, not the source (generator). The generator will have its own protection.

It's not a big deal to utilize something that is oversized, like running 30A through a 50A receptacle. Where you'll run into problems is if something is undersized, like a cable or breaker. In that case you'd constantly trip the breaker or have to worry about melting that cable.
