Asking for a plugin: Post Specific Names

Hi everyone!

I just wandered: maybe there is a way to do the same thing as with Avatars ( www.proboards.com/library/plugins/item/696 ) but with Displayed Names ('user')? 

I've tried all of these Plugins:
www.proboards.com/library/plugins/item/598
www.proboards.com/library/plugins/item/282
www.proboards.com/library/plugins/item/160
www.proboards.com/library/plugins/item/1080
- but this is all limited to Admin/Moders manual work, and also the amount of 'masks' is not relevant for my needs.

Maybe creating another line in a similar manner, but instead of a link- for a Custom Avatar in each post, it would replace User-name (shown in that same post); or maybe these two fields can be replaced altogether somehow. Basically, creating a 'mask', that members can use in every post without any Admin interference at all (no need to be manually added via Plugin page).

It can be very useful for cross-roleplay for example, where every member sometimes needs 5-10 different masks for character-swapping, or for Diary-alike thread where aesthetics for each post can be different). 

I saw a full Mask-Script on MyBB platform (where you can change Name, Avatar, Status, Signature and Custom Fields, and keep up to 12~ or so masks in a drop-box next to Reply Field, individual to each member, without any Admin interference, no attachment to a forum's storage etc), but that system has completely different structure and functionality (and is also a Russian platform), so there is no way to adopt it for ProBoards system (I've tried). I can show you that script (RU source) if interested (Google Translate does a decent job) as a reference (screens or text). 

Hopefully someone had the same request at some point (or already have their own way to do the same thing I've asker for with existing Plugins or CSS).

Thanks in advance! x
