You can try using the "-n" flag for r.proj to avoid region clipping or
you can extend your region beyond the edges of the zone.

Hello GRASS users-
I am trying to create a mosaic of LANDSAT taken of Eastern Hudson
Bay area using GRASS 6.3.0. I have run into the problem though that
some of these images are from different UTM zones (16, 17, and 18).
Currently, I have been able to import images from the three UTM
zones into 3 different locations. What I want to do is bring in the
images from zones 16 and 18 (currently imported into different
locations), and patch them with images from zone 17. I have tried
re-projecting these images into the location for zone 17 using
r.proj, but when I do this, it cuts off parts of the images which
are not within zone 17.
I have looked at previous posts on the forum, and have found some
advice (moving raster maps across UTM zone boundaries). I have
never used shell script and am very new to GRASS, so the advice
given in this response is somewhat complex for me. Are there any
suggestions of how best to mosaic images from different zones
without using shell script?
Thanks in advance for any help,
Renae Mackas
