Join / merge free spaces of Hard Drives into one file

Hi,
I don't even know how to google this.
I have 3 hard drives
Drive 1: 250gb free - ntfs
Drive 2: 200gb free - ext4
Drive 3: 50gb free - ext 4 - another pc on LAN (usually I use sshfs to store stuff there)

Is it possible to create like a file on each, bind each other, and mount somewhere?
My objective is to create 1 file of 500GB size without moving files, resizing partitions, buying more hard drives, nor etc.
Is it possible?

Thank you.

As a theoretical exercise you could create an empty file on filesystem occupying the space you want,  convert the files to block devices with losetup,  then follow LVM to create a single filesystem spanning the three files.

In practice I would never attempt this.
