If that comes to pass I am definitely going to get rid of my exposure to FTSE 100, if the Saudis don't want their oil any more why should I ?
As far as I am aware the plan was only to list 5% of Aramco, so the market cap would "only" be around £50B, perhaps £75B on a very optimistic valuation. I don't think the Saudis are particularly keen on listing any of it, but are doing so to raise capital in order to reform their economy.
Holding a large allocation of FTSE100 companies is foolhardy anyway IMHO. Far better to globally diversify and cap UK companies at say 25% at most. I currently cap the FTSE 350 to 10% of my global equities portfolio and overweight FTSE 250.
