Can we change the Brake Fluid this way?

[lamadoo]

Instead of removing the tyres and bleeding the brakes is it possible to

-Turkey suction the old fluid out as much as possible
-Refill it with new fluid
-Drive the car for a few months so it can mix with the old fluid trapped in the system
-Repeat the process again of sucking the brake fluid out and refilling it
-Do this again every 6 months.

I'm a beginner when it comes to DIY and lifting the yaris with four jacks to remove the tyres and then bleeding it without getting any air inside it sounds really intimidating
