I agree with Andrew: get a heat exchanger/plate chiller. Your glycol system is (probably) designed to hold volumes at a set temperature and, over time, bring that temp down if need be as at the end of fermentation (around 71°F) down to crashing temp (around 31°F). Don't risk your tank by messing around with trying to maintain pressure in hopes of staving off an implosion.
In addition to beers, I also make craft sofas so I understand what you are trying to do. The hot/warm sugar mix is a PERFECT environment to grow the horrible bacterial nasties (HBN) we are all trying to avoid in the brewhouse and cellar. Boiling this mixture for a duration is a great way to prevent this but you must crash the liquid's temperature as fast as you can from boil kettle to storage tank and a heat exchanger/plate chiller is the way to do this. Relying on your tank's glycol jackets is just too slow and could give the HBN the foothold they need to propagate and ruin your brew, at a minimum. My two cents.
