Wedding advice/ideas?

Hi guys! 
So I have always found the tradition of the dad giving away his daughter somewhat.... creepy...
I always wanted my grandmother to walk me down the aisle because her marriage with my grandfather resembles so much of that with my fiance's (met when they were young and have been together until he died) sort of like a "good luck" type of thing. She also raised me when my mother kicked me out at 14. 
However... She unfortunately passed before this could happen, before I was even engaged. 
I'm wondering if you guys have any ideas on how to still incoporate her in "walking me down the aisle". 
Also, how I could explain this idea to my father and maybe include him in a different way? I don't know, personal choices I guess but just the thought of him "giving me" like cattle to my fiancé seems very weird, and I'm not his to "give". I don't want to hurt his feelings though. :/
