Using speaker cable as jumpers

Hello, everyone
I'm kind of new in this forums, and I guess I will ask something already spoken here a couple of years ago.
I have a pair of Martin Logan's Ascent bought 2nd hand but the jumpers they "bring are 2 pieces of thick copper (pretty much oxidated). I'm wondering if I can/should replace them by Kimber 8TC (which are the cables I'm using with them).

Any suggestions / opinions will be pretty much apreciated.

Thanks
