It's a fine idea, Epic, but technically outstanding to implement in mIRC's current incarnation and framework.
The suggestion as presented would require a major re-write of mIRC and prove to be a massive undertaking.
There are other clients that already focus more on client aesthetics and decoration that you might experiment with.
Not sure that mIRC really needs to copycat those efforts to present as a desirable and reliable client in its own right.
