I did try to do it myself, but with no success: here is what i tried:
in .Xresources i put #include "/home/<USER>/.config/wal/templates/xresources-dwm"
and i added the file xresources-dwm to the ~/.config/wal/templates directory with the contents:

dwm.normbordercolor: {color8}
dwm.normbgcolor: {color0}
dwm.normfgcolor: {color15}
dwm.selbordercolor: {color15}
dwm.selbgcolor: {color2}
dwm.selfgcolor: {color15}

but it doesn't work.
