How would one trim/prune a massive ficus tree?

Is it even possible? I have a pretty messy cluster of strangler fig tree that I think is a Ficus Benjamina. As far as I can tell there are six major trunks with diameter exceeding 24" in an area about 30'X30' in my yard. Over the years it has grown into each other where branches and aerial roots fused together into an interconnecting mass. I bought the property two years ago and at that time the branches have spread over to two oak trees 25 feet away on my neighbor's yard and it

They all can produce areal roots and strangle whatever they wrap around.. " Strangler " Fig is just an over - used, common reference for these species of Ficus.. Using the scientific name narrows things down a whole lot better. Native sp. would be F. aurea, and F. citrifolia. F. benjamina would be the non native species.. Much smaller leaves than either of the natives, ..even on mature trees.. F. benjamina: https://www.inaturalist.org/taxa/50996-Ficus-benjamina F. citri
