  A key theorem of Yakimov's proves that the torus-invariant prime spectra of
De Concini-Kac-Procesi algebras are isomorphic as partially ordered sets to
corresponding Bruhat order intervals of Weyl groups. We present examples of
more general Cauchon-Goodearl-Letzter (CGL) extensions which exhibit this same
phenomenon. To accomplish this, we develop a procedure for iteratively
constructing poset isomorphisms between torus-invariant prime spectra of CGL
extensions and Bruhat order intervals of Coxeter groups.
