I can see that would be useful, provided you have all of the accessories. I do see an error in the plumbing. The fitting string between two fixed points in a system needs to have a bit of adjustment to allow for tightening the various components. The top plate has been bent by the fittings. Using a bulkhead fitting in an elongated hole would provide acceptable adjustment in this situation.

The schematic is pretty straight forward.
