Wazifas

Q: I have the habit of reciting aayat ul kursi (once) followed by the last three surahs 3 times each and then doing a dum on myself and my family members who are living in other places and countries by imagining their faces one by one and doing dum in the approximate direction. 

I would generally do that amal at any time of the day with the intention of safety and well-being of myself and the loved ones. I would like to know:

2. Is there any added significance and benefit of continuing this practice compared to normal masnoon prayers for self and family members? 

3. Or whether it's an innovation and should be avoided?
