Porting to WP4.x

trying to run MiniMU version 0.6.9 on WP4.5 i have to see that it is just not possible to select tags for subsites in the MiniMU settings.

is there any chance to update/port this extension?
I would go into offering gratificatin for making it functional for WP4.x
(Since it would some non-commercial projects save a lot of work maintaining nearly identical sites, excecpt for local theme etc.)

Anywone interested? Either in cofunding or simply making an offer for the job.
