Both of them (separate/separated) are adjectives. Are they any discrepant?

Can I use 'discrepant' in the predicative position of a sentence?

Thanks.

Both of them (separate/separated) are adjectives.-- I cannot choose, because neither seems to make sense in your sentence. What do you want to say?

Are they any discrepant? Can I use 'discrepant' in the predicative position of a sentence?-- Not with 'any'.

I have to say that I've gone more than 40 years in my life without ever encountering the word "discrepant."
