Hi , as you have already correctly mentioned, you will have issues with wing icing top/bottom of the wing, so de-icing will need to happen. You won't be pumping any warm fuel into the wing because you have just tankard the fuel. Fuel freeze temperatures will need to be considered but Jet A1 can go as low as -45c. If your landing heavy because of the extra fuel and the runway is contaminated you could be Landing performance limited.
Your not allowed to tanker fuel when the runway is classed as contaminated (company SOP may differ).
