Paralleling filters is not a safe thing to do.? Many too many unpredictable things happen.
Also the filter impedance is around 500-650 ohms.??
A 9:1 impedance transformer would get you close and efficiently.? Next integer version is 16:1.
A 9:1 would be close enough for low loss (under 1.5db for two using 61 material).
An L network works easier.
