I hope not for security reasons :)

from man ifconfig in freebsd 5.3 BETA6 

^^^^^^^^^^^^^^ 
txpower power
For IEEE 802.11 wireless interfaces, set the power used to trans-
mit frames.  The power argument is a unitless value in the range
0 to 100 that is interpreted by drivers to derive a device-spe-
cific value.  Out of range values are truncated.  Typically only
a few discreet power settings are available and the driver will
use the setting closest to the specified value.  Not all adaptors
support changing the transmit power.

^^^^^^^^^^^

since 5.3 might be the next stable relaese you need to rewrite the 4.9
driver for monowall and hack it into it. Or wait:
a. next 5.x stable release
b. monowall to actually use this release.
