how to swap input interfaces with each other without using switch or if block?

eg. I have four input interfaces H1,H2,H3 & H4. So based on some valid condition i have to swap these signals like this (H4->H1,H3->H2,H2->H3,H1->H4). I had implemented this using switch block but since i have so many interfaces, it is creating mess in the code as well as design also. Is there any alternative way to implement optimized design for this? Implemented image is attached.

Use a MATLAB Function block. You will be writing if else if or switch statements as if you were writing it on MATLAB command line.
