You can but it involves command line stuff to re-spend the coins with a higher fee, one will go through and the other will be denied as its a double spend. Tricky stuff, maybe someone's come up with an easy way but you'd be better off just waiting for it to go through, could take a couple of days but it will get there eventually.
I started a topic about this yesterday - unfortunately it is *not* possible to do what you are suggesting as once the network has *seen* the original UTXO being *spent* (regardless of being confirmed) it will *reject* any attempt to "double spend" (including forwarding such attempts).
You could only successfully achieve such an approach if (i) you can send the tx to a part of the network that has not yet seen the spend or (ii) the network has dropped the tx (which it might after a certain amount of time although that could be days).
