How to improve ubr10k?

Hi everyone,

I would like to have some advice from the community on how to improve our Ubr10k. In my company we want to enable new nodes and I was wondering if is better to still get the most of the MC5X20 card adding other cards and equipments or go for the MC3Gx60V card. Below is an inventory of my Ubr10k, any advice or list of items to improve would be appreciated.
