No point in doing the cilex if you’ve done a LLB and LLM. The only benefit I could see is if you didn’t get good grades and you’re topping up.
I dunno what opportunities pakistan would provide even as a lawyer. Don’t lawyers in pakistan normally end up dead? In the UK a LLB/LLM would open up all routes ranging from banking to accounting & business. Maybe you should stay here and do your LPC, and find a TC.
If you enjoy studying, why not just use your LLB/LLM and teach law at university or lower schools.
