I don’t think bad- is particularly well suited here it might have been replaced by pad-; in any case, I think ego is most appropriate here. The imperative of mib- would be mibo “kiss!”, the overlong vowel would only appear in the third person mîb ‘he/she/it kisses’ (compare how the imperative of ped- is pedo and the third person is pêd). Thus Ego! Mibo orch (or alternatively Mýtho orch with a different reconstruction for “to kiss”)
