No.  Do not do this.  This is the exact opposite of the advice the government will give you.  The correct advice is: do not book any travel until you have received your visa.

No DO NOT book any flights until AFTER your visa has been issued and you have checked it for errors. UKVI advise not to book any travel until you have received your visa, so it won't help the processing time. It takes as long as it takes to be processed, regardless of whether you've booked flights.

You don't want to buy a flight only to find the visa isn't issued in time or it is refused and then you lose all the money you've spent.
