Do you think the girls name -Patricia, could make a come back in todays "trendy society"?

I think Patricia will make a comeback, but probably not for another 20 years or so. There are two things working in its favor right now: 1) Patty sounds a lot like Maddie and Addie, both popular nicknames right now (and similar-sounding names tend to run in generations); and 2) there are a lot of young men named Patrick right now. If they want to name a child after themselves and have only daughters, then Patricia is the logical choice.
