sure -
sqlplus /nolog

alter system checkpoint;
alter system archive log current;
shutdown abort
startup restrict
shutdown immediate

<run your cold backup job>

startup
quit

you now have a consistent backup set - and you didn't even have to put any tablespaces in backup mode - and it won't require any recovery.

if that it not what you wanted, then you must change what you want. "hot" or "consistent" are mutually exclusive concepts.
