How to recreate these pages from an expired domain without using the same ugly permalink structure for the whole website?

So I bought an expired domain that fits my niche perfectly for a new site I'm gonna build.

The domain has some interesting backlinks I want to take advantage of. I've read it's good practice to restore the pages/posts that these links are pointing at, at least for a while.

The issue is that the domain used an "ugly" permalink structure that I don't want to use on the new site I'm gonna build.
F.ex. the URL of the posts on the old site is like this: domain.com/index.php/category/post

I really don't want to use a permanent permalink structure where I have "index.php" as a part of all the URLs.
But how can I then restore the posts from the old domain that used this structure? Is it possible at all, or what are my alternatives?

For what it's worth all the URLs of the old domain are still index in Google. Does this mean I can skip the restoration part and just add a 301 to the homepage instead?
Or can I remake the post with with a more common permalink (like domain.com/OriginalPostName) and then 301 the domain.com/index.php/category/post to this post?

It is recommended that you set up the site to be exactly as it was then till Google restores the backlinks (i.e the backlinks start showing up on GSC).
