i'd toss the front rim and maybe use the rear rim. maybe.
let's say you're if you're heeled over in a turn and concentrating on contact patch location, deciding
on when/how much to throttle up, looking for mid-corner sand or bumps that'll unsettle your old shocks/noodle frame, and gobs of other stuff. while your brain is collecting input and making incremental adjustments and compensations, do you really want to add the worry of maybe a spoke pulling thru or loosening?
spend the money on solid rims, new spokes and the best tires you can afford. and no, i'm not a effete snob with wads o'cash laying about but i do know how to lessen my odds of laying her down. .015
