Changing Interlinking strucutre of growing website

I have been working upon my website. Bought PBN service and PBNs have been drip feeding over the past 3 months and will drip feed daily over next 30 days.

Now website traffic is also increasing now.

Current interlinking is surely not related. But Should I mess with this…
