could use some advice

I might be committing a newbie error here but I'm not sure where to place this, I'm sorry. Please do move it or direct me to existing threads if need be.

I have two WIPs which are both moving along more quickly than I'd expected them to. The time is soon approaching for me to begin queries. WIP #1 is a nonfiction history work. WIP #2 is a humor novel.

I know the rules and etiquettes for agent queries, and the issues with simultaneous subs, etc., but my question is this:

Would it be out of line to send nonfiction WIP #1 to the history editor at Yale University Press, who doesn't require one to have an agent, while at the same time querying WIP #2, the novel, to agents?

The history project might be a good fit and well-suited to YUP, while the novel would definitely not be (it's just a rompy book of fun). Two very different bits of work.

In no way do I want to go about things incorrectly, which is why I'm asking here. Any advice will be most appreciated.

Very grateful, thank you all for responding. I was afraid I had one of those looks-good-on-paper ideas that are best left untried.

This is reassuring, as query time is looming ever larger in the side-mirrors of my life. Querying always makes me feel like the Fuller Brush salesman, and not in a good way. Plus I haven't done it in about a century or so. Gah.

Thanks again, very much.
