Not to my knowledge. The thing that makes them 'deep' cycle is plenty of lead & I don't think there's a market for a smaller flooded deep cycle. Most of them are made for golf carts, off grid power storage, etc.

Seems the SLAs are working for you & you're keeping an eye on things. There are also AGM (absorbed glass matt) batteries as an alternative. I suspect SLAs use similar technology. Like SLAs, AGMs tend to be a bit pricier than the traditional flooded type.
