Would you change titles of category pages for utilizing breadcrumb?

I am thinking of utilizing breadcrumb.

The website is a Wordpress blog that see ~ 60k visits a day with 1300 posts and 30 categories.

It’s been a while since I realized the SEO importance of this type of navigation and its effectiveness to readers.
The problem is that most titles of the category pages are long tails (and it doesn’t look nice to implement a long tail link in breadcrumb).
Long tail in these pages was a mistake that has been done since the beginning days of the site. Plus, these category pages get organic traffic! - In some pages thousands of direct visits.
Now the dilemma is – would you change (at list some) of these pages title.
* Not all of them see high volume of traffic.
It is a risk – losing of ranking not only on these pages but also on posts linked to them.

What do you think?

Not a risk in my experience.

Just redirect all requests for the old category to the new category. I did something similar for a site with around half a million URLs. I changed the folder (/folder/) from the old name it's had for ten years or so to a completely new folder (/newfolder/) with zero long term problem. All inbound links still worked because the URLs simply redirected, so for all intents and purposes the URLs stayed the same as far as Google and sites linking to the old folder were concerned. The only thing that changed was one part of the URL (example.com/folder/) and a redirect corrected that (example.com/newfolder/. As I recall, at the time, it took Google about ten days to fully re-index the new URLs.

Thanks Martin for your answer it's a good example what you did.

However, in my case, I don't think of changing the URLs structure but the titles. Changing title tag might have negative impact on the page ranking.
I am still hesitating.
