if the transaction is rejected. i think it is better not to rebroadcast it? am i right?
because when it is rebroadcast, if stuck again, then need to wait again. am i right?
but if when rebroadcast and get confirmed then that is great.
i will not try the double spend way. because i have read some testimoni that is not easy.
You send me a PM so I will post my view here. The inputs has a high (> 1 BTC) value and thus has a chance (even though its low) to get confirmed without a fee. Since this is the easiest solution that does not require anyone handling any unprotected private keys and you appear to be rather helpless in terms of private keys. I will rebroadcast the raw tx[1] every 10 minutes with my node. This makes sure that the transaction is well known within the network and gives it a higher chance to get confirmed. If its confirmed or you rather want to try a more complex double spend please send me a PM so I can stop the script.

Like altcoinhosting said, it is do-able, but all steps must be done correctly in order to get it done. I think shorena's option is the best, but by far not the quickest, because u need luck that ur transaction will get confirmed. If shorena's option doesn't workout, I would do a double spend, but first let's wait for shorena.
Also don't send anyone your private keys, not even to trusted people.
