Can you use an implement in each hand?
Yes.
Can you use both on the same spell?
No.
That's my take on it, anyway.

Multiple magic items that take up different 'slots' should all be able to work at the same time. However, two items using the same slot [implement] is the question at the moment.
Dualwielding pact blades is different though, one would be dual wielding them as weapons, but could only wield one as an implement. However, it's listed as a weapon that can act as an implement, allowing it to apply it's property as a weapon twice [since you would get the benefit of both wielded weapons].
Besides, why kick what is generally considered the weakest class in the junk again while all the melee folk are running around with their frost weapons.
