Batch Spam Musubi tips?

I’m tasked with making 3 dozen spam musubi for my kid’s team snacks.

Question about the rice… we have a smallish rice cooker, and one batch of rice isn’t enough. Last time, we needed to do it in three batches, which is pain in the early morning (need to get up early).

For spam musubi, will it lose much quality if I make all the rice the night before and just reheat it in the morning?

We have a good recipe we like and a double wide musubi mold. Other tips or techniques are welcome! thanks.
