There is already an RFE about this.
I posted in said RFE the following combination. It differs from yours in that b & n are SW & SE rather than n & m; this saves having to rebind use special power.
Code:
y k u
\ | /
h - . - l
/ | \
b j n
Also from that post:
Keybindings that have to be changed:
'u'se tool - rebound to \CU
'h'andle something - rebound to \Ch
'k'ick something - rebound to \Ck => requires rebinding of 'toggle (more) prompt' key. I bound it to \C\S, but it doesn't work, so I still have to find a good combination for that.
examine environment ('l') - rebound to x (makes more sense anyway)
'n'ame something - rebound to \Cn
and from another post after it turns out the above is broken on non-Windows platforms (because there is no difference between \CU and \Cu). Of course, I myself can't use these keybindings because alt is used as a modifier for my window manager.
'K'ick
Display 'm'issile, 'w'eapon and 'k'ick statistics are all bound to :\C<quoted key> [yes, this means :<return> displays missile statistics].
toggle (more) prompt is back at \Ck
use tool is \Mu (alt-u)
display experience is \Mx (alt-x)
