Can I use these grammar structures in conversations?
I'm a Buddhist priest, so sometimes I talk with the temple members in a formal(ish) way. Considering this, is it ok for me to use these grammar structures? Or do I sound weird or too literary if I use these grammar structures in daily conversations?

1) "Whether or not TO do something" instead of "whether or not I do something"
2) Doing A would be a tough thing to do, AS WOULD doing B. (no subject between "as" and "would")

I came up with these questions when I was reading the definition of the word "crucible" on Vocabulary.com.

Answer

I think it is perfectly OK to use both of these.

Answer

2 is normal.

For 1, these are the natural options that come to mind 
e.g. I don't know whether to go out or not.
e.g. I don't know whether I should go out or not.

"whether or not + infinitive / subject phrase" is OK but more formal.  I tested them on my wife and she independently came up with the same structures as me.
