You do not need a custom ROM for that. Rooting will suffice. The you can remove all you want (for example, using Titanium Backup). More importantly, you do not really need to completely remove the apps. While the entire iOS is just a glorified app launcher, Android is a more evolved OS. It shows all apps only in the special App Drawer while allowing users to customize their main pages as they want. You can easily remove any bloatware from the main pages and it will never bother you again.
