This wouldn't help at all. The system page cache (which is dropped by the above action) will only use memory that would otherwise be unused.
I.O.W. if the system would ever run low on memory, then this cache is the first to be reduced/dropped automagically by the kernel.
Really: there is no silver bullet. Find out where the memory is used excessively and why. Then change exactly there.
