Look at some marine toilets. Some have a macerator without the pump. They are generally not very aesthetically pleasing for a home, tho.

Also for a standard home macerating toilet, there really isn't any reason you can't pump it down. Typically those exit through the wall behind the toilet, and there's no reason it has to go up you can just redirect it down.

If you pump down, gravity and siphoning will prevent the check valve from closing of it is a flap style. It needs to eject into a larger vented pipe above pump level to prevent the siphon. An open check valve would allow sewer gas to enter.

I would hope he properly vents it and there should still be water in the bowl to seal the gases out.

This is interesting. I will be appropriately venting. Seems like that would be the only issue. Also looks like I can hide the box in the wall on some of the models.
