Won't such double spending have negative consequences? Did anybody tried it?

This wont be a double spend, because it is impossible to double spend ;) Blockchain.info (or someone else) might log double spend attempts, but I can't really think of any 'punishment' by doing so :)

Nodes that already know about the first transaction will not relay your double spend attempt, and the possibility of success depends on quirks such as a miner not knowing of the original transaction due to a restart and then takes the double spend attempt as it seemed to be legit.  Suggesting a double spend as a workaround is not good advice.

Is it possible to increase the transaction fee of a sent transaction not yet in a block?

Today? No.

There was a feature that was developed referred to as [child pays for parent](https://github.com/bitcoin/bitcoin/pull/1647) however few miners if any are using this patch.

There have been instances where mining pool operators have been offered a bounty to include a specific transactions, but there is no automated process for that and presumably would require a significant incentive.
