Ubuntu phone on FP1, (similar hardware as the Aquaris E4.5 Ubuntu)

There is indeed this heise online article (I’m not sure, if it is the one, @GT-Eins is referring to) from February 2016, which states the following:

English translation: Even with the first Fairphone the company hasn’t given up hope yet to provide a newer Android and alternative OSes and is still working on a solution.

I still think that there is a theoretical possibility that there can be a Ubuntu Touch port for the FP1 because we have already experienced two community ports on an Android Kitkat codebase (CM11 and Kitkat 4.4.4 by @chrmhoffmann) and I can’t imagine why a company, which could pay a developer full time for porting an OS and has obtained the software licenses to be legally able to, couldn’t come up with alternative OSes.
