You can use trademarks without permission, you can disclaim the origin to avoid any possibility of confusion. AIUI EU courts have frowned on attempts to extend copyright using trademarks. It feels like a lewd art piece would clearly not be from Disney in any case so trademark really wouldn't be an issue. I learnt v.recently that UK copyright since 2015 has allowed parody and pastiche (following an EU directive from ~2001), so with a disclaimer on origin you might be able to have your Mickey manga right now? I guess it will depend on whether Disney can buy another copyright extension in the USA and pay off enough people to push those changes to other jurisdictions based on very spurious notions that we somehow have to harmonise with USA. This is not legal advice and in no way relates to my employment.
