(1)  ANSI.SYS assumes 25 line screens (even in EGA/43 or VGA/50 line mode).  You
will definately need one of the replacements.

(2)  Lines/screen is located in 40h:84h.  If you change that to 21, a modified
ANSI.SYS might scroll properly.  Programs that write directly to the screen or
use BIOS to position the cursor will probably not be affected.  Clear Screen
(CLS / Esc [ 2 J) will probably clear the entire screen.  Of course, your
program to update the status bar may break.  (Why do you need THREE status
lines?)

(3)  I am curious if this will work.
