Changing out Spades

Hello -

I recently purchased Clarus Crimson biwire speaker cables. However, their spades are too wide to fit my Vandersteen Quatro Speakers. 

The barrier strips on the Quatro's allow for 7/16" max width, spades on the Clarus are 1/2". I thought I could squeeze them in somehow but can't.

So, I'm considering purchasing Audioquest 507 Series Multi-Spades to change out to. I was assured by Audioquest that those spades do fit in the Quatro barrier strip. My plan was to simply cut off the existing spades on the Clarus cables, peel a bit of casing back, and mount the Audioquest spades. 

Is there anything wrong or concerning with doing this?

Thank you for any response!
