Freedom Permalinks can help you to change permalinks to any format you want. 
Update slug structure, change domains, remove/add slashes or add extensions (.html, .php or anything you want) etc.
<pre><code>PS. While this gives you freedom to play with permalinks, you should know that you have to make those link structures work with your themes yourself.
</code></pre>
For example if your theme is installed on subdomain1.domain.com, changing permalink to subdomain2.domain.com will break the existing links and you have to move your theme manually to subdomain2.domain.com to make it work.
<pre><code>Things you must know before trying this plugin:
1. It's best suited for custom/smaller themes.
2. Always create backup of your database before trying this plugin.

The Multiple Domains with Analytics plugin allows WordPress to be mirrored across multiple domain names. This requires your DNS settings to be configured ahead of time so that all of your domain names point to the same location. While configuring DNS settings in this way will point all visitors to the same site regardless of domain name, any interaction on the page (clicking an internal link) will revert back to the base domain name that exists in the WordPress general options. This plugin allows the domain name that was initially used by the visitor to stay constant as well as display a customizeable Name and Tagline for the duration of their visit. In addition, this plugin can include separate Google Analytics codes to track the traffic to each domain.
Full list of features:
<ul>
<li>Unlimited number of mirrored domains.</li>
<li>Customization for Site Title, Tagline, Analytics Code and URL for each domain.</li>
<li>Can be used with or without another Google Analytics plugin, it’s your choice.</li>
<li>If enabled, this plugin uses the asynchronous Google Analytics tracking code, the fastest and most reliable tracking code Google Analytics offers.</li>
<li>Option to ignore logged in users when Google Analytics is enabled.</li>
</ul>
