Then we make a wrapper function. Something like
GetUndeletedColumnByName(relid,attname)
replaces SearchSysCache(ATTNAME,...) in those places where you don't
want to see deleted columns. It'd return NULL if it finds a column
tuple but sees it's deleted.
GetUndeletedColumnByNum(relid,attnum)
replaces SearchSysCache(ATTNUM,...) similarly.

That would mean duplicate storage of tuples inside the catcache...
