In general, it isn't a good idea to parallel uC pins, however if you pay careful attention to the timing on the pins and what you are driving, then it can work.
Firstly, you should try and ensure both pins switch at the same time. So writing to those port pins using BSF/BCF will result in temporary shorts, so you need to suck in the value of the port, modify the value, then write it out. Or you could use boolean logic.
I haven't written for the 16 series for a good few years, but something like-
turnon:
movlw 0x00110000
iorwf PORTC
turnoff:
movlw 0x11001111
andwf PORTC
Personally, I'd bolt on a 2N7002 and use just one pin.
