Sounds like good progress and hopefully a great result. If it works out for you, could be a reasonable $ fix.
If I already owned the same vintage of coach, I would have been getting very creative myself with this type of upgrade. Something I would like to note for those Newell Coach owners whom have these type of headlights that are plastic, if they are becoming yellowed, you can usually increase the performance by polishing away the yellow on the lense. I have done this over the years to several plastic headlights by using a good buffer and some 3M heavy duty compound. It only takes a couple of minutes to perform. A lot of people will replace composite headlight assy. due to the yellowing.
