More recent editions of mc have the mod "little tiles" and "chisels and bits" which allow you to place what are somewhat similar but better to classic microblocks. Little time iirc lets you go down to a 1/128th of a block.
You may also like the conquest reforged mod. It has a huge number of textures and archetecture elements. The cocricot mod and texture pack are very good if you would like to make something more modern. Here are a couple links of examples for things done with chisels and bits and little tiles
