One date as mahr

Q: Is it permissible to me to ask for 1 date for my mahr? I would like to ask my fiancee to go to the poorest date seller, ask him how
much 1 kg of dates cost (f.e. 10 Dinar) and ask him how many family member he has (f.e. with him included there are 6 people living with him) so my fiancee should multiply the cost of 1kg of dates with the family members (inc. the date seller). f.e. 60 Dinars. So I want my fiancee to pay the date seller 60 Dinars, but take only 1 Date as my mahr and leave the others to the date seller as a sadaqa. I would like to eat the date with my fiancee's mother and my mother, and plant it to a tree (in shaa allah). I also would ask (as part of my mahr) for the surah mulk to get recited by him from his heart.

Is this permissible that he give me this 1 date + reciting one surah under such extraordinary circumstances? Or is the mahr void if I just ask for that?
