Do you have a link to a credible source that mentions the Rolls-Royce Ultrafan being a potential candidate for an Airbus A380 re-engine? All of your information above comes with absolutely no source, apart from a whole bunch of apparent hearsay.
Found the Airbus press release https://www.airbus.com/newsroom/press-r ... labor.html
“UltraFan features a new engine core architecture and lean-burn combustion system which will contribute to improved fuel burn efficiency and lower emissions, along with a carbon titanium fan blade system and composite casing which reduce weight. The engine also introduces a geared design to deliver efficient power at high-bypass ratios.
For Airbus, the project will enable it to fully integrate the overall powerplant system – composed of engine, pylon and nacelle – onto future long-range aircraft products, as well as facilitating scalability for future short-range aircraft. It will also build on Airbus’ expertise in advanced manufacturing technologies, such as high-deposition-rate additive manufacture, welded assembly and high production rate thermoplastics.”

“R-R, for its part, is Airbus's sole engine supplier for the A350 and A330neo, and will provide its Trent 900 engine for remaining A380 orders.
East says the UltraFan programme – which involves a new engine core and geared fan architecture – is scalable to provide 25,000-100,000lb-plus (111kN-446kN) of thrust, making it suitable to power single-aisle and long-haul aircraft.
The first opportunity to provide an UltraFan variant will probably be on a long-haul aircraft, with the A350 being a likely candidate for a potential re-engining effort, East says.”
“New engines planned by Rolls-Royce (R-R) reflect recent powerplant trends, including steadily increasing propulsive efficiency obtained with larger-diameter fans, higher bypass ratios and smaller engine cores. The engines could power updated contemporary widebody platforms, with R-R civil large engines president Eric Schulz confirming “very live” discussions with Airbus. “If it decides to re-engine the A330 or A380, we will be here to provide support,” he said during a pre-show briefing.”
“Expected to follow about five years later, the UltraFan is aimed at offering at least a 15:1 bypass ratio and an overall pressure ratio of more than 70:1. The company suggests that, relative to the Trent 700 powering the Airbus A330, the engines will provide “significant efficiency improvements” of more than 20 percent and 25 percent, respectively. R-R plans to run its first powered gearbox next year and a demonstrator of the engine could fly before 2020.”

An A380 re-engine is so improbable as to induce incredulous laughter even in the most diehard Airbus fanboy.
I guarantee you the first airframe to have an ultrafan installed will be the A380, it will be the flight test platform.
