You could get many of the features you mention by using a cacheing program, of 
which there are many available; my favorite is PC-KWIK, available shareware
from a variety of sources.
    The main limitation of caches is that since DOS can't run a synching 
process, writes can't be cached.  Typically one reads far more than one writes,
so this isn't a major disadvantage.
    I tested PC-KWIK in a disk search, and found ~12x performance improvement
with ~100k devoted to cacheing.
