No. 말다 means intentionally not doing something. -지 말다 cannot be used with an adjective directly because adjectives can't represent an intentional action. For most emotion-related adjectives, there is a corresponding verb in the -아/어하다 form which can be used with -지 말다. For example, - 슬프다(a), 슬퍼하다(v) -> 슬프지 마(X), 슬퍼하지 마(O) = Don't be/feel sad. - 좋다(a), 좋아하다(v) -> 좋지 마(X), 좋아하지 마(O) = Don't rejoice. - 아쉽다(a), 아쉬워하다(v) -> 아쉽지 마(X), 아쉬워하지 마(O) = Don't feel sorry. In each of these examples, the first phrase (marked X) with the adjective sounds strange and unnatural.
