Marion Ecker of Murphys designs does some splitting for EL. Don't know if yours is in the list, or if you could ask for it. Some cost, some are free, according to the page. EL seems to take a bit to answer sometimes.

Contact them, I think they have a site to go to that splits designs for you. When you contact the site, that's where you get the best answers to the issue.
I just looked at the clock design, I would think any of the ones that are under 7 inches, since you only have a 5x7 hoop. But I have not ever split a design myself. Hopefully someone else can help you better. Good luck. Have a blessed day.
