You can try that, but it isn't likely to yield results. It's like watering potted plants without putting the seeds in. Most of the tossed grass seeds sit on top of the soil or existing grass blades and never germinate. The seeds need to make it into the soil, just like growing a potted plant. The best way to accomplish this is to aerate your lawn first, then overseed.

Technically, yes—and you may have some successful growth—but this isn’t the ideal way to fill in sparse areas. By clearing leaves and debris, amending the soil, and aerating it properly before you lay the seeds, you’re providing the most ideal conditions for them to germinate.

In the fall, you should aerate the soil, overseed the bare spots, kill weeds, mow the lawn low, and rake your leaves. By boosting your lawn’s health in the fall, your grass will be stronger throughout the winter and come back healthier in the spring. You should also trim your perennials so that they withstand the winter and are ready for new growth in the spring. 

Make your ryegrass thicker by boosting soil health. Add organic matter, aerate the lawn if the soil is compacted, fertilize appropriately, and see if your lawn needs dethatching.
