Can I do this?

This is how I'd like to layout my bathroom in my soon to be finished basement...

Black is what I have now with grey showing the sewer line under the slab...

Red is what I'd like to do...

Any issues with that?

Updated: Can I do this?

venting outside to the roof is not really an option... This will be the basement of a 2 1/2 storey house built in 1911 with a finished loft in the attic... Do you have any other recomendations for venting?

Update:

I pulled the cap to the cleanout tonight and looked down with a flashlight...

The cleanout goes down at about a 45-degree angle about two feet under the slab where it has a horizontal Y with one going out to the street and the other to the rear of my house to the stack...

This means that i can put everything wherever I want with more than enough room for slope... Could I perhaps rather than digging all the way to the main line, instead run a Y off the vertical pipe that runs to the cleanout and just dump the toilet and sink into there... Otherwise I have to dig 2 feet down just to get to the main...

Any word from the pros?
