An interesting proposal, though less general on the terminal due
to space available and alignment considerations.

Note you can sort of hack it now with LS_COLORS like:

LS_COLORS='lc=:rc=:rs=:'
LS_COLORS="${LS_COLORS}di=🗀 :fi=🗋 :ln=  :do=  :cd=  :bd=  :so=  :pi=  :"
LS_COLORS="${LS_COLORS}ex=:tw=:ow=:st=:su=:sg=:"
export LS_COLORS

Which generates nicely aligned output on my terminal at least:
For example: ls /proc/$$

🗀 attr               cwd      🗋 loginuid    🗋 numa_maps      🗋 schedstat  🗀 task
🗋 autogroup        🗋 environ  🗀 map_files   🗋 oom_adj        🗋 sessionid  🗋 
timers
🗋 auxv               exe      🗋 maps        🗋 oom_score      🗋 setgroups  🗋 
timerslack_ns
🗋 cgroup           🗀 fd       🗋 mem         🗋 oom_score_adj  🗋 smaps      🗋 
uid_map
🗋 clear_refs       🗀 fdinfo   🗋 mountinfo   🗋 pagemap        🗋 stack      🗋 
wchan
🗋 cmdline          🗋 gid_map  🗋 mounts      🗋 personality    🗋 stat
🗋 comm             🗋 io       🗋 mountstats  🗋 projid_map     🗋 statm
🗋 coredump_filter  🗋 latency  🗀 net           root           🗋 status
🗋 cpuset           🗋 limits   🗀 ns          🗋 sched          🗋 syscall
