My haunted chairs; fabric advice

A few weekends ago I was driving through Georgetown and stumbled upon an estate sale.  I've been attending a lot of these lately in order to feather my new nest and was excited to find a set of 4 18th century English dining chairs which I was able to scoop up for a bargain as it was the last day of the sale.

The chairs have seen better days and need a good cleaning and polishing (Murphys oil soap and some furniture polish) and the upholstery contains 40 years of dust and grime (or whats left of the upholstery). But the chairs are sturdy and in excellent condition otherwise and of a diminutive scale perfect for my apartment.  One chair is in such bad condition that I'm just leaving it in my storage unit for another future owner to deal with -and here is where the story begins!

Unbeknownst to me, the house is one that hosted a media frenzy a year ago when a society matron was murdered by her much younger husband.  Years before the murder, some violence forshadowed the death involving a chair.  My chair with the horribly bashed in corner perhaps??? oh my! That chair  will forever be called my haunted chair and will stay untouched in my storage unit!
However, whats to be done with the 3 others? In my posession I have a length of grey cashmere upholstery fabric from Ralph Lauren Home as well as beautiful plaid wool, also from Ralph Lauren.  I'm thinking of using the plaid but thought I would ask some of you what you thought?  Orange plaid, grey cashmere or something new?
