I have been reading these boards for quite a while and they have been super helpful at times of need in the past as I just managed to search most of my issues without even registering

I have a specific question this time around though. Any help would be much appreciated.
I am a naturalized British citizen of Sub continent origins. My father who is a widower is dependent on me financially and emotionally as I am his only child. He has been visiting me on a visit visa for last 7 years or so. Never overstayed or anything. Last time when he came over to visit me about 1.5 years ago he fell very ill to a point where it became a life and death situation. I have so far managed to get all his health care done privately. So about a year ago I applied through a lawyer for a discretionary leave for my father to be able to stay with me long term. Home Office obviously rejected it and we are going to first tier tribunal next year May. From the looks of it the system is rigged and there is very little chance of getting a visa for him.
I got married to a French girl last month after a 4 year long relationship.
My question is that can I apply for my father to be dependent of my EEA spouse even though I am a British citizen myself?
My fathers passport is still with the Home Office and he is still living in the UK waiting for a decision on his discretionary leave application.
This is what the Uk gov website says:
"Qualifying as a family member
You must be the EEA citizen’s spouse or civil partner, or related to them (or their spouse or civil partner) as their:
child or grandchild under 21 years old, or dependent child or grandchild of any age
dependent parent or grandparent"
Thank you very much
