Transfer Fortnite acc?

So I have to realese of fortnite on switch it mor brought back then there was still no crossplay, therefore, I have to create a new acc. Now it is well known yes and wanted to ask if I can transfer my ps4 acc aif switch (or vice versa) without my existing skins emotes etc. Lose.

Now you can transfer it all even though you played switch before that

Then I lose my skins
