Technically speaking, is it possible to reuse a change address from a previous transaction and make it a receive address?

What are the pros and cons of doing so? This does look like a bad privacy practice, but I wonder whether there would be any rationale for doing this.

Are there any wallets that currently support this functionality?

Technically that would be possible. The network rules have no concept of change or receive addresses - it's just a scriptPubKey that coins are sent to.

I see no reason why you'd want to do that. It's bad for privacy as it's gratuitously exposing linkage between transactions.

Are there any wallets that currently support this functionality?

I hope not.
