Unlikely. She was way too decisive, not like Churchill who was universally loved.
They'll true and make one for political reasons though. Cameron would a) love a Tory state funeral and b) Headlines of stupid ex-Union members and Labour politicians saying stupid things about her.
It'd be a disaster but not necessarily a political one. We'll see what her family want I suppose, they might be more savvy than that.
--------------------------------------
Thatcher herself did a lot right but she was too stubborn to see where policies had really negative effects and to mitigate those. In the end though every PM since her has failed to identify areas of the UK that have seen negative or stagnant growth since her time in power.
Its very simple really - Labour created Social Housing around state industry; when that was removed, the Social Housing should have been drastically reformed.
I won't blame her as its not like anyone 'fixed' the underlying problem of the most unemployed people getting housing in the areas of lowest employment, but she did ignore the people really hurting, taking the Tory view to desensitize themselves to any plight they suffer.
I do commend her for having a belief and seeing it through. These days Tories just parrot old ideas without believing/understanding them. And I can tell you - that brings a lot more negatives that anything she reformed.
It really is having their cake and eating it that Thatcher is not a celebration of British Feminism though.
