in the default rlxtools.rlx file you will find
<rl:manipulator name='lowres' suffix='pdf'>
<rl:old><rl:value name='path'/>/<rl:value name='file'/></rl:old>
<rl:new><rl:value name='path'/>/<rl:value
name='prefix'/><rl:value name='file'/></rl:new>
<rl:step>
texmfstart pstopdf --convert --method=4
--inputpath=<rl:value name='path'/>
--outputpath=<rl:value name='path'/>/<rl:value name='prefix'/>
<rl:value name='file'/>
</rl:step>
</rl:manipulator>
so, what you can do is define something lowres-x and lowres-y and set
the conversion to one of those those depending on the width
tricky but kind of okay is
\definemeasure[whatever][\makeupwidth]
...
width=\measure{whatever},conversion=lowres-\ifdim\measure{whatever}<\makeupwidth
x\else y\fi,...
