Rereading this... I probably got you wrong and you want some char lines and then some border color "area" ($ff19) and then some chair lines again. If I remember correctly, it's possible to "re-initialize" a complete new "text window" by manipulating $ff1d (and probably some other registers).
Some demos obviously used this method for scrollers in the upper and lower border. (Not sure but I think Crown's Magic Picture Show works like this.)
Furthermore, making the "text window" smaller and thus gaining some cycles is possible (this was discussed here in the early days of XeO3).
