Bruce I been trying believe it or not to make a kit to replace these boards with old school controls.
That's interesting. In the past week or so I've had 5 cases of Whirlpool 4448868 control boards with very worn out displays. These are from model series: KEBI206, KEBI241, KEBI276, KEBS107, etc.
The displays are custom made and I've been searching for a way to get the mfr to source me some, no luck... But I've been thinking there may be an alternative board (or as you are thinking -an old school control kit) that could salvage these units.
I'd be interested in discussing this further with you.
