We dry hop our pale in CCV all the time.
It is a process to capture the aroma (oil) fraction at such cold temperatures. It takes time...or...we circulate the CCV every day for 15 minutes over a minimum of three days. Speeds the process immensely at such temperatures.
You can also try daily rousing with CO2 from the centre cone but foaming in the tank may be an issue.
I don't think that this will help with your yeast settling issue.
You may wish to consider fining or filtration for this batch.
