Okay, so basically encoding the zone in the easting? Better, but I still think it is weird. At least it produces somewhat sane output.
Is that operation used by any CRS in the EPSG database?

(…snip…) I'd consider the UTM zone a part of the OUTPUT, whereas you seem to consider it part of the required input (lat, long & UTM zone).
So in my case:
in: lat & long
out: UTM zone, easting & northing.
so the process would look more like:
$ echo 6 51 | proj +proj=utm +zone=auto
31 710488.86 5654109.18
Actually such operation already exists in EPSG database (not sure if it exists in Proj4 however). This is the Operation Method EPSG::9824 - Transverse Mercator Zoned Grid System. The output is basically:
E = Z*10^6 + (result of projection for zone Z)
This is not widely used however.
