Except for the kol isha part, there is no inherent issur on the rest of it. They, however, make a big shor of what they are doing, and as Shakespeare said, “The PLAY’S the thing…” If they were truly doing it to serve Hashem out of a great spiritual need, they would do it in an acceptable way.
As to the Tefillin, there is no issur for women to wear them, but there is no obligation, either. If they are doing the mitzvos they are chayavos in, with the same zeal and zrizus as they are putting into their phoniness with the Tefillin, then I have nothing to object to, except for the Chillul Hashem of their public display, of course.
