Walaikumussalam brother
May Allah accept your aamal and ibadaat in this holy month
May Allah grant greatest place to Sayyed Fadlallah in Jannah
You are doing his taqleed he is not alive and I have not seen his ruling for the specific situation which you mentioned
As per the ruling of current maraje like Aayatullah seestani
Any act which causes to help or propagate the falsehood it is haram.
As you mentioned if you feel that in anyway it leads to assist or propagate the baatil or assistance to shirk then refrain from it.
Wassalam
