Is it possible to implement my specific partition table on linux? [on hold]

Ok sorry if my question is confusing.
I am using Ubuntu with Linux sources: linux-4.15.0
In my project, I have a specific device, the partitioning of this device is not editable and it requires a custom partition tables which need to be located at
the end of the device with custom partition structures.
I searched the Linux kernel how to put my partition table so that linux can, when it detects my device, put me in /dev/sbd1 ... according to the number of present partitions.
I would like to create regions for these partitions. But when I search where I can parse my specific partition, I notice that I have to modify the kernel
sources(/block/partitions/check.c " *static int (*check_part)(struct parsed_partitions*)*").
There is no means to register a new partition parser callback as the array is statically defined against kernel configuration.
I do not want to change the kernel sources (adding my partition table parser and modifying the array)... I would like to provide instead a mechanism to detect this specific partition tables using a loadable module. (so that the kernel sources are not directly impacted)
I hope I should not add my custom block device driver ...
So, is it possible to implement my specific partition table ?
Thank you

This is all a bit confusing… Why does your filesystem have its own partition table? What exactly are you trying to implement (file system/partitioning scheme/device driver/multiple of the above) and what/who are you developing this for?
