Is it dangerous to connect an IC output directly to GND?
Instead of adding junk on the output of your buffer, just use an AND gate instead. 

For example, 74LVC1G08 or 74LVC2G08, which have the same 32 mA output drive capability as the 74LVC2G125 you're using now.

If you need the Schmitt trigger feature on the input, and the negative enable logic, you can combine a Schmitt trigger inverter and a NOR gate:
