Bad wishes in Jannah

It is said that in jannah one shall get whatever he want and in Jannah all wishes will be fulfilled as mentioned in the Quran , however in this world we have some desires that are not appropriate and are harmful , I have read people saying that in Jannah we will not make these wishes as our minds will be purified , but my Question is that , do these harmful things have to be the same in Jannah ?, I don't think so ... I mean they can turn harmless and good in Jannah thus not being considered bad anymore (but the experience can be same or better), since Allah can do anything he can turn the possible harmful things into appropriate and harmless , one mentioned is the wine that is turned good and appropriate in Jannah for believers to experience it,... can this transformation from bad to good not happen to all other possible bad things , (only things that are possible to be turn good). so that one can experience these in heaven . I think it does not make complete sense that "our minds will be purified so we won't make all these Bad desires " I think this can only be said to some specific evil things that have no chance to be turned good and pure in Jannah . for example if one loves boxing in this world and it is harmful in this world , but in jannah can he not make the wish for boxing , and experience it in a permissible harmless form , may be something like a video game(just an example) or any other way , (since Allah can do anything) ,
