Does slow effect from Carronade stack with freeze?

I can not switch talents on swift ATM to test this but I'm curious if Carronading an enemy THEN freezing them would keep both slowing effects intact and possibly slow them to a crawl for a few seconds enough to big torpedo them.
Also how viable is carronade now at high infamy play?

Edit: Looking at Swift's tree more closely, the slow effect lasts for 3 seconds only, so the slow effect would be gone by the time you cycle to frost blaster.
It is only possible if two friendlies co ordinated their carronade and freeze simultaneously, so a very slim chance of it happening.

 

I there is only one case: blast , carro, torp. Pretty sure your frost should be broken by carro.
In another case carro, blast , torp - slow from carro disappear just in a launching time for torp.
Don’t see any nightmare player with this setup. Fire, ex more easy and profitable)) that’s all folks)

 

They will not stack. The carronade shot will break the frost (blaster or launcher) effect and leave only the carro frost effect(s) (speed and turret rotation). The carronade effects themselves will stack and last after the unfriend in question takes a hit. But the stack will only last for about 1 second.

The carronade frost is nearly impossible for one to make use of on their own. It only slows for 3 seconds and that's about 1 second longer than the global cooldown. The slow really only lasts long enough to let you pass by a boat that your pretty close to (for speeders atleast). So, yeah it's better for well co-ordinated combo attacks. But here's a tip, fire the weapon that you want to hit the unfriend with before you fire your carronade. Timed well enough, you can land the carronade hit just before the weapon hits. Good luck though, the move is anything but easy to pull off.
