When people overwrite things that are basic like that they usually don't have an alternative. They overwrite them, because it doesn't fit their common usage pattern.

But, for example, I use ',' as my <Leader>. So that I can still use ',', I also map ',,' back to ',' functionality:

  let mapleader = ","
  let maplocalleader = ","
  nnoremap <leader>, :normal ,<CR>:<CR>
