Howling:Is the Bubble Universe really e-space?

Could the Bubble Universe featured in The Doctors Wife actually be e-space? From the events of Logopolis we know that one of CVE's to e-space was left permently open. Could this be the rift the doctor travels through in ''The Doctors Wife? ''The Doctor also describes the bubble universe as being like a plughole universe though which stuff falls through, which kinda fits the discribtion of e-space with the entropy being funneled into it.
