This engine seems to have just one vent tube, is this enough? Could

this

one be eliminated and just use the one on the center housing?

Apparently so. I don't know of anybody that has increased the  size of

the

oil pan vent or had any trouble with oil pan venting.
Blow by the oil seals on a Mazda does not seem to be as big a
problem as it is on piston engines.

The one near the oil dipstick is enough Wendell. Re your photogragh I

was

advised by my engine builder not to bolt the coil assemblies to the

engine.

Too much heat and vibration.

Either one is sufficient but I get less oil venting during aerobatics when I
used the one directly into the centerhousing.
