What you ask is not possible at the moment. I would love to be able to set aliases on the various fields and still be able to use WFS-T, it's been on my wish list for quite some time, with some databases, like for example Oracle, there is simply no way to avoid very ugly names on fields in the db. That said, doing what you ask requires setting up a new wrapping data store that can do the field name translation forwards (when serving data) and backwards (to turn the filters and field name requests back in their native names before hitting the actual data source). And then configuration and GUI to allow changing the names, and test a lot to make sure it's not breaking anything. Doable, but quite a sizeable chunk of work too. I'm waiting for sponsoring to show up to do it, it's too big to fit in spare time coding (done in spare time it would eat up all weekends for a few months).
