Could 'Oumuamua be an icy fractal aggregate ejected from a protoplanetary disk?

Oh it would be crazy expensive. But we have the tech. (Wait, do we have tech for in-orbit refueling? Anyway we're developing that for Mars missions already so we'll have it soon.)

We resupply the international space station, so even if we couldn't carry great loads of fuel up at a time, orbital refueling is clearly within the realm of the possible.

More interesting would be if we could beam up energy to refuel, but for that we'd probably need yet-to-be-invented drives which use loads of energy per amount of matter to accelerate it further. Kind of like a particle collider but for propulsion.

My bet would be an RTG powering a dozen electric thrusters packing a lot of propellant and a relatively small probe.

Still, it'd mean reaching Uranus' orbit in about a year. That's a lot to ask for.
