I don't think it is a good idea to parallel the pins.
What about start-up?
I will at least make space for some diodes, some thing like a BAV70LT1 OR
BAW56LT, depending on sink or source. These are two diodes in a sot23 common
cathode or anode.

Perhaps just to be super safe, instead of toggling the pins on and off,
toggle them on and then tristate them. That way you'd be sure you
wouldn't have one up and one down.

Just an idea.
