Generally, the two modifiers joined by a comma will be PARALLEL IN FORM and will serve the SAME GRAMMATICAL PURPOSE.
Proposed construction:Question 2:
Can an adjective modifiers comes after an Appositive modifier and relate to same NOUN?
NOUN + COMMA + APPOSITIVE + COMMA + ADJECTIVE
This construction is not viable if the appositive and adjective are both intended to refer to the preceding noun.
For two noun modifiers connected solely by a comma to have the same referent, they must be parallel in form.
