That won’t solve any problem that LaTeX macros solve. Boilerplate in LaTeX has 2 purposes.
The first is to factor frequently-used complex notations. To do this in Markdown you’d need to bolt on a macro preprocessor on top of Markdown.
The second one is to fine-tune typography and layout details (tables are a big offender). This is something that simply cannot be done in Markdown. A table is a table and if you don’t like the style (which is most of the time inadequate) then there is no solution.
