Those RIFA capacitors are for EMI/EMC purposes.

You can omit them when verifying equipment's general operation, but to ensure performance in a high-sensitivity analogue instrument you may need to replace then.

New X2 caps are easy to find. I would replace them and that's it.

X1 caps are just as easy to find and are better rated.   For a few pennies more, why not?
