No.
Just like with the power supply and clock oscillator pins, the peripheral switch matrix options per pin are defined by the silicon. The possible configuration options per pin are given in the datasheet.
Alternatively, you could use a larger package, or implement some functionality by "bit-banging" (like a "software UART").
