Old style pull chain with new wallmount toilet?

[Corvinus]

I'm designing my new bathroom and have a blank canvas with which to work since the entire thing is gutted and I am just about to the place where I begin plumbing. I love mixing the old with the new and wanted to install a wall mount toilet, but I want to use the old Thomas Crapper Valveless Waste Preventer box instead of a tank mounted in the wall. Anyone see any major problems or challenges in incorporating the two?
