Can Kinetis K60 MII RXER, CRS, COL pins that are unused be repurposed?

I'm trying to figure out whether I can repurpose the MII0_RXERR, MII0_CRS, or MII0_COL pins in my design on a MK60FN1M0VMD12. The pins presently would not be connected externally to anything but ground. I'm connecting it to a switch which has an MII port and will not have those signals.

Can any of those pins be set to another function (such as FTM, or IO) rather than seemingly being wasted inputs from ground?
